The procedures for setting the peripheral module function are described below.
1. Select the peripheral module by using the peripheral module select register 1 (P1MSELR) and
2. When an input or input/output pin is used, it is necessary to set the pull-up MOS for each pin
3. Write B'00 to the corresponding two bits in the port control registers (PACR to PRCR).
peripheral module select register 2 (P2MSELR).
by using the port pull-up control registers (PEPUPR, PHPUPR, PJPUPR, PKPUPR. PLPUPR,
PMPUPR, and PNPUPR). Write B'0 (when the pull-up MOS is off ) or B'1 (when the pull-up
MOS is on) to the corresponding bit. When an output port is used, the pull-up MOS is off
regardless of the settings of the port pull-up control registers.
