RISC-V mconfigptr CSR Register

Address 0xF15Privilege MachineAccess RO / XLENMachine implementation and hart identification CSRs

mconfigptr (0xF15) is a mandatory MXLEN-bit read-only Machine CSR holding the physical address of a configuration data structure.

Understand mconfigptr By Bit Fields

1 key fields
XLEN-1:0

VALUE

RO

Physical address of the configuration data structure. If MXLEN=8×n, mconfigptr[log2(n)-1:0] must be zero; the structure's format and schema have not yet been standardized.

VALUE (bits XLEN-1:0) — Physical address of the configuration data structure. If MXLEN=8×n, mconfigptr[log2(n)-1:0] must be zero; the structure's format and schema have not yet been standardized.

What This Field Controls

  • - Physical address of the configuration data structure. If MXLEN=8×n, mconfigptr[log2(n)-1:0] must be zero; the structure's format and schema have not yet been standardized.

Common Values

This field is better understood together with surrounding context than as a fixed memorized enumeration.

What To Check First When Reading This CSR

  • - This CSR must be readable in any implementation; its CSR address encoding requires Machine-mode access.

Risk Checks Before Writing

  • - This is a read-only CSR; do not write it.
