Interrupt Mask
Range: 0000 to FFFF hex
Bits 0 to 15 correspond to each interrupt task. The meaning of the individual flags is
as follows:
0: Interrupt enabled (unmasked).
1: Interrupt disabled (masked).
Range: 0000 to 00FF hex
Bits 0 to 7 correspond to each interrupt task. The meaning of the individual flags is
as follows:
0: Interrupt enabled (unmasked).
1: Interrupt disabled (masked).
0000 hex: Interrupts enabled (unmasked) in direct mode.
0001 hex: Interrupts disabled (masked) in direct mode.
0002 hex: Interrupts enabled for decrementing counter in counter mode.
0003 hex: Interrupts enabled for incrementing counter in counter mode.
