Interrupt Controller
7.2.2
ICR1–ICR4 are used to configure interrupts from various on- and off-chip sources. When read, the data is
the last value written to the register with the exception of the PI bits, which are transitory functions. These
registers can be accessed as 8-, 16-, or 32-bit registers. An 8- or 16-bit write leaves the remaining bits
intact. To avoid altering other IPL fields when resetting interrupts generated by INT[6:1], read the
required byte, word, or longword from the appropriate ICR, AND.B/W/L its value with a mask whose IPL
bits are all 1 and whose PI bits are 1 for those sources whose PI bit is to be reset and 0 for those sources
whose PI bit is to be left unchanged.

Pending interrupt. Writing a 1 enables the value for the corresponding IPL field to be set. Note: for
external interrupts only, writing a one to this bit clears the corresponding interrupt latch. The external
interrupt must be toggled before another interrupt is latched. For all on-chip interrupt sources, this bit
is cleared when the interrupt is cleared in the module registers.
0 No interrupt pending
1 An interrupt is pending.
Interrupt priority level. Specifies the IPL for the corresponding interrupt source. This field can be
changed only when a 1 is simultaneously written to the corresponding PI bit.
000 The corresponding INT source is inhibited and cannot generate interrupts. The state of the signal
001–111The corresponding INT source is enabled and generates an interrupt with the indicated priority
level.
