mintstatus was the Current Interrupt Levels CSR in the CLIC v0.10 draft at historical address 0xFB1; current ACLIC v0.19 and the privileged CSR table no longer define that name.

Official Basis & Search Notes

mintstatus belongs only to the historical official CLIC v0.10 draft. ACLIC v0.19 no longer defines the name, so this page provides no current-standard fields or access semantics.

CLIC v0.10 lists mintstatus at 0xFB1.
ACLIC v0.19 instead defines the different mistatus CSR at 0x346; mistatus is not an alias for mintstatus.
The current privileged CSR table does not allocate the name; this page does not present old draft behavior as a current standard.

What To Check First When Reading This CSR

  • - ACLIC v0.19 instead defines the different mistatus CSR at 0x346; mistatus is not an alias for mintstatus.
  • - CLIC v0.10 moved the draft mintstatus address to 0xFB1; the former page value 0x346 was obsolete.
  • - Check the published extension version implemented by the target; do not infer a current CSR from this old name.

Risk Checks Before Writing

  • - Do not access this old draft CSR in portable code targeting current standards.
  • - ACLIC v0.19 does not define mintstatus at 0xFB1; verify the implemented extension version before accessing any draft CSR.

Put It Back Into A Real Flow

1

Confirm that the reference explicitly targets CLIC v0.10.

2

Check the historical address and the newer A-CLIC definition of that address.

3

For a current target, use only the extension and CSR set that the implementation declares.

FAQ

Is mintstatus a current standard CSR?

No. It appears in the CLIC v0.10 draft, but ACLIC v0.19 and the current privileged CSR table no longer define the name.
