10. Interrupt Controller (INTC)
10.7.2
When the IRQ/IRL[7:0] pin functions are switched, the INTC may retain an incorrectly detected
interrupt request. Therefore, mask the IRL and IRQ interrupt requests before switching the
IRQ/IRL[7:0] pin functions.

Procedure
Write 1 to all bits in INTMSK0 and
INTMSK1 except reserved bits
Write 0 to the PMSEL14 bit in PMSELR
Write 0 to the PL4MD1, PL4MD0,
PL3MD1, PL3MD0, PL2MD1, PL2MD0,
PL1MD1, PL1MD0 bits in PLCR
Set bits IRLM1 to IRLM0 in ICR0
Write 1 to the corresponding bit in
INTMSKCLR0 and INTMSKCLR1
