Fields

`ADDR`

Location: pmpaddr60[63:0]
Description: Bits PHYS_ADDR_WIDTH-1:2 of the address specifier for PMP entry 60 (or, if pmp61cfg.A == TOR, for PMP entry 61).
Type

RO	Read-Only Field has a hardwired value that does not change. Writes to an RO field are ignored.

Reset value

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 csr_value.ADDR;
}

Software read

This CSR may return a value that is different from what is stored in hardware.
