•  P16/PO14/TIOCA2/EDRAK2/SSCK0-A 
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. 
•  Modes 1, 2, and 4 Modes 3 and 7 (EXPE = 1)
