COMMON INTERRUPT MASK BIT DESCRIPTIONS
A 1 written to any of the bits in these common interrupt mask registers, and a 1 state for the corresponding
latched alarm bit of the same channel in registers 0B1H and 0B7H, causes a hardware interrupt to occur on
the INT/IRQ output lead if control bit INTEN (bit 2 in register 0C2H) is set to 1.
PER CHANNEL INTERRUPT MASK BIT DESCRIPTIONS
A 1 written to any of the bits in these per channel interrupt mask registers (except HINT), and a 1 state for the
corresponding latched alarm bit of the same channel in registers XB1H, XB3H, XB5H (Bits 5-0), and XB7H,
causes a software interrupt (SINT) to occur for the channel. If the hardware interrupt bit (HINT) is also written
with a 1, and if control bit INTEN (bit 2 in 0C2H) is set to 1, a hardware interrupt will also occur on the INT/IRQ
output lead.
Where X=1, 2, or 3, which corresponds to the selected channel:

Mask for Interrupt Indication for Channel n: A 1 written to a bit enables
the corresponding latched status alarm INTn in register 0B1H to cause a
hardware interrupt.
Mask for Add Bus Contention: A 1 written to this location enables the
corresponding status alarm ADBCN in register 0B7H to cause a hardware
interrupt.
