Description
Indicates that the I
interrupt request to the CPU.
IRIC is set at different times depending on the FS bit in
SAR, the FSX bit in SARX, and the WAIT bit in ICMR.
See section 18.4.7, IRIC Setting Timing and SCL
Control. The conditions under which IRIC is set also
differ depending on the setting of the ACKE bit in
ICCR.
