Bits in the G1IR register are not automatically set to 0 (no interrupt requested) even if a requested inter-
rupt is acknowledged. Set each bit to 0 by program after the interrupt requests are verified.
The IC/OC interrupt is generated when any bit in the G1IR register is set to 1 (interrupt requested) after all
the bits are set to 0. If conditions to generate an interrupt are met when the G1IR register holds the value
other than 00
request again, clear the G1IR register to 00
register to 0.
Figure 20.4 shows an example of IC/OC interrupt i processing.
