msrset

Read MSR and set bits in MSR

Description

Copies the contents of the special purpose register MSR into register rD.

Bit positions in the IMM value that are 1 are set in the MSR. Bit positions that are 0 in the

IMM value are left untouched.

Pseudocode

(rD) ← (MSR)

(MSR)

← (MSR) ∨ (IMM)

Registers Altered

• rD

• MSR

Latency

1 cycle

Note

MSRSET will affect some MSR bits immediately (e.g. Carry) while the remaining bits will

The immediate values has to be less than 2

. Only bits 18 to 31 of the MSR can be set.
