LCSR Programming Model

Interrupt Level Register 4 (bits 16-23)

ADR/SIZ			$FFF40084 (8 bits [6 used] of 32)

BIT	23	22	21	20	19	18		17		16

NAME			VIRQ6				VIRQ5 LEVEL

OPER			R/W					R/W

RESET			0 PSL					0 PSL

This register is used to define the level of the VMEbus IRQ5 interrupt and the VMEbus IRQ6 interrupt. The VMEbus level 5 (IRQ5) interrupt and the VMEbus level 6 (IRQ6) interrupt may be mapped to any local bus interrupt level.

VIRQ5 LEVEL These bits define the level of the VMEbus IRQ5 interrupt.

VIRQ6 LEVEL These bits define the level of the VMEbus IRQ6 interrupt.

Interrupt Level Register 4 (bits 8-15)

ADR/SIZ			$FFF40084 (8 bits [6 used] of 32)
BIT	15	14	13	12	11	10		9		8

NAME			VIRQ4				VIRQ3 LEVEL

OPER			R/W					R/W

RESET			0 PSL					0 PSL

This register is used to define the level of the VMEbus IRQ3 interrupt and the VMEbus IRQ4 interrupt. The VMEbus level 3 (IRQ3) interrupt and the VMEbus level 4 (IRQ4) interrupt may be mapped to any local bus interrupt level.

VIRQ3 LEVEL These bits define the level of the VMEbus IRQ3 interrupt.

VIRQ4 LEVEL These bits define the level of the VMEbus IRQ4 interrupt.
