Interrupt Controller Registers
7.2.2 Interrupt Control Registers (ICR1–ICR4)
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.
7.2.2.1 Interrupt Control Register 1 (ICR1)
ICR1, Figure 7-2, is used to configure interrupts from various on- and off-chip sources.
Table 7-3 describes ICR1 fields.
