Delegates Instruction Address Misaligned exceptions to (H)S-mode. Instruction Address Misaligned exceptions may be futher delegated to VS-mode if hedeleg.IAM is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Instruction Access Fault exceptions to (H)S-mode. Instruction Access Fault exceptions may be futher delegated to VS-mode if hedeleg.IAM is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Illegal Instruction exceptions to (H)S-mode. Illegal Instruction exceptions may be futher delegated to VS-mode if hedeleg.II is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Breakpoint exceptions to (H)S-mode. Breakpoint exceptions may be futher delegated to VS-mode if hedeleg.B is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Load Address Misaligned exceptions to (H)S-mode. Load Address Misaligned exceptions may be futher delegated to VS-mode if hedeleg.LAM is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

Note that because this implementation supports misaligned loads, this exception will never occur. However, the writeable bit should be presented anyway.

The handling mode is determined as follows:

Delegates Load Access Fault exceptions to (H)S-mode. Load Access Fault exceptions may be futher delegated to VS-mode if hedeleg.LAF is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Store/AMO Address Misaligned exceptions to (H)S-mode. Store/AMO Address Misaligned exceptions may be futher delegated to VS-mode if hedeleg.SAM is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

Note that beause the implementation supports misaligned stores and misaligned AMOs (or no AMOs), this exception will never occur. Even so, the writeable bit should be presented anyway.

The handling mode is determined as follows:

Delegates Store/AMO Access Fault exceptions to (H)S-mode. Store/AMO Access Fault exceptions may be futher delegated to VS-mode if hedeleg.SAM is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Environment Call from U-mode exceptions to (H)S-mode. Enviornment Call from U-mode exceptions may be futher delegated to VS-mode if hedeleg.EU is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Environment Call from S-mode exceptions to (H)S-mode. Enviornment Call from S-mode exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Environment Call from VS-mode exceptions to (H)S-mode. Enviornment Call from S-mode exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

An Environment Call from M-mode cannot be delegated, so this is a read-only field.

All Enviornment Call from M-mode exceptions are taken by M-mode.

Delegates Instruction Page Fault exceptions to (H)S-mode. Instruction Page Fault exceptions may be futher delegated to VS-mode if hedeleg.IPF is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Load Page Fault exceptions to (H)S-mode. Load Page Fault exceptions may be futher delegated to VS-mode if hedeleg.LPF is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Store/AMO Page Fault exceptions to (H)S-mode. Store/AMO Page Fault exceptions may be futher delegated to VS-mode if hedeleg.SPF is also set.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Instruction Guest Page Fault exceptions to (H)S-mode. Instruction Guest Page Fault exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Load Guest Page Fault exceptions to (H)S-mode. Load Guest Page Fault exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Virtual Instruction exceptions to (H)S-mode. Virtual Instruction exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:

Delegates Store/AMO Guest Page Fault exceptions to (H)S-mode. Store/AMO Guest Page Fault exceptions cannot be delegated to VS-mode.

Exceptions are never taken into a less-privileged mode, regardless of medeleg.

The handling mode is determined as follows:
