Pin function
The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, TPU channel 2 settings (by bits MD3 to MD0 in TMDR_2, bits IOA3 to
IOA0 in TIOR_2, and bits CCLR1 and CCLR0 in TCR_2), bit NDER14 in NDERH of the
PPG, bit EDRAKE in EDMDR_2 of the EXDMAC, bits MSS and SCKS in SSCRH and bit
SSUMS in SSCRL of the SSU, bits SSCK0S1 and SSCK0S0 in PFCR5, and bit P16DDR.
