interrupt source codes for the IRL and IRQ pins and the priority level of the GPIO interrupt, refer
to section 9, Interrupt Controller (INTC).
24.2.22 Port A Pull-Up Control Register (PAPUPR)
PAPUPR is an 8-bit readable/writable register that individually controls the pull-up for pins PTA7
to PTA2 corresponding to each bit in the register when the given pin is used by a peripheral
module. However, for the pins set to the GPIO in the PACR, the settings in this register will be
invalid.

24.2.23 Port B Pull-Up Control Register (PBPUPR)
PBPUPR is an 8-bit readable/writable register that individually controls the pull-up for pins PTB7
to PTB1 corresponding to each bit in the register when the given pin is used by a peripheral
module. However, for the pins set to the GPIO in the PBCR, the settings in this register will be
invalid.
