Appendix B: Register Details
Register (mpcore) ICDICFR4
Register ICDICFR4 Details
The ICDICFR 4 register control the interrupt sensitivity of the Shared Peripheral Interrupts (SPI), IRQ ID
#64 to ID #79. This register has two bits per interrupt. This two bit field is either equal to 01 (high-level
active) or equal to 11 (rising-edge sensitive). The LSB is always 1 because only one CPU will handle a SPI
interrupt, regardless of the number of CPUs targeted.
Refer to UG585 TRM Section 7.2.3 Shared Peripheral Interrupts (SPI) for the required sensitivity type for
the SPI interrupts. The SPI interrupts must match the expected sensitivity. Interrupts from the PL may be
high-level or rising edge sensitive; this must be coordinated with the PL hardware and software.
