interrupt mask register codes
Instruction Description: This instruction selectively sets the Interrupt Mask register ac-
cording to the interrupt mask code x. For each bit set to "I" in x, the corresponding bit
position in the Interrupt Mask register is set to "I" (see Table 7-8). Bit positions repre-
senting missing or nonavailable I/O channels cannot be set.
