The remote control signal receiver shares interrupt vectors or interrupt control registers with other
peripheral functions. To use remote control signal receiver 0 interrupt, set the IFSR24 bit in the IFSR2A
register to 1 (remote control signal receiver 0). To use remote control signal receiver 1 interrupt, set the
IFSR25 bit in the IFSR2A register to 1 (remote control signal receiver 1).
The IR bit in registers PMC0IC and PMC1IC is different from another IR bit in the following respects:
•If the interrupt enable bit in the PMCiCON2 or PMCiINT register is 1, the IR bit in the PMCiIC register
becomes 1 (interrupt request) when the corresponding interrupt request signal is generated.
• If multiple interrupts are enabled, IR bit becomes 1 and then remains 1 when another request source
is generated.
• The IR bit does not become 0 automatically when the interrupt is accepted. Set the IR bit to 0 within
interrupt routine.
