NOTES:
1. Do not change the interrupt enable bit (bits 1 to 7 in the IIOiIE register (i = 0 to 11)) and the IRLT bit in the IIOiIE register
2. If an interrupt request is generated while writing a 0 to the corresponding interrupt request flag, the flag may not be cleared to
3. Ensure that all the enabled interrupt request flags are set to 0. If any of these flags remains 1, the IR bit in the IIOiIC (CANkIC
IIO8IR register = 00h
IIO8IE register: IRLT bit = 1
IIO8IE register: PO11E bit = 1
IIO8IC register: bits ILVL2 to ILVL0
I flag = 1
IIO8IR register: PO11R bit = 0
IIO8IR register: PO23R bit = 0
simultaneously. Set the IRLT bit to 1 first, and then set the interrupt enable bit to 1.
