pmpaddr13[63:0]
- Description
-
Bits PHYS_ADDR_WIDTH-1:2 of the address specifier for PMP entry 13 (or, if
pmp14cfg.A
== TOR, for PMP entry 14). - Type
RW |
Read-Write Field is writable by software. Any value that fits in the field is acceptable and shall be retained for subsequent reads. |

UNDEFINED_LEGAL
- Software write
-
This field has special behavior when written by software (e.g., through csrrw).
When software tries to write
csr_value
, the field will be written with the return value of the function below.if (csr_value.ADDR >= (14)) { return UNDEFINED_LEGAL_DETERMINISTIC; } else { return UNDEFINED_LEGAL_DETERMINISTIC; }
Software read
This CSR may return a value that is different from what is stored in hardware.
