Freescale Semiconductor
Operation:
1
⇒ I bit
Description:
Sets the I mask bit. This instruction is assembled as ORCC #$10. The
ORCC instruction can be used to set any combination of bits in the CCR in
one operation. When the I bit is set, all maskable interrupts are inhibited,
and the CPU will recognize only non-maskable interrupt sources or an SWI.
