Interrupt Registers
This section provides information on the registers that are used to config-
ure and control interrupts. These registers are:
• "Interrupt Register (LIRPTL)" on page B-6
• "Interrupt Latch Register (IRPTL)" on page B-13
• "Interrupt Mask Register (IMASK)" on page B-18
• "Interrupt Mask Pointer Register (IMASKP)" on page B-22

Interrupt Register (LIRPTL)

with the proper operation of the interrupt controller.
The interrupt bits 0 through 19 are programmable through the program-
mable interrupt controller registers (
their default sources. For information on their optional use, see
