Local Bus Interrupter Status Register (bits 8-15)

ADR/SIZ			$FFF40068 (8 bits of 32)

BIT	15	14	13	12	11	10	9	8

NAME	SW7	SW6	SW5	SW4	SW3	SW2	SW1	SW0

OPER	R	R	R	R	R	R	R	R

RESET	0 PSL	0 PSL	0 PSL	0 PSL	0 PSL	0 PSL	0 PSL	0 PSL

This register is the local bus interrupter status register. When an interrupt status bit is high, a local bus interrupt is being generated. When an interrupt status bit is low, a local interrupt is not being generated. The interrupt status bits are:

SW0	Software 0 interrupt.
SW1	Software 1 interrupt.
SW2	Software 2 interrupt.
SW3	Software 3 interrupt.
SW4	Software 4 interrupt.
SW5	Software 5 interrupt.
SW6	Software 6 interrupt.
SW7	Software 7 interrupt.
