Interrupt Controller Registers
Table 7-3 describes ICR3 fields.
7.2.2.4 Interrupt Control Register 4 (ICR4)
ICR4, Figure 7-5, is used to configure interrupts from various on-chip sources.
Table 7-3 describes ICR4 fields.
7.2.3 Interrupt Source Register (ISR)
The interrupt source register (ISR), Figure 7-6, is used to read the instantaneous value of
all interrupt sources, both internal and external. Note that the register bits give the value of
the interrupt source prior to input synchronization or polarity correction.
