Pin function
The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, bit WAITE in BCR of the bus controller, bits MSS, CSS1, and CSS0 in
SSCRH and bit SSUMS in SSCRL of the SSU, bits TRGS1, TRGS0, and EXTRGS in
ADCR_0 of the ADC, bits ADTRG0S and WAITS in PFCR4, bits SCS0S1 and SCS0S0 in
PFCR5, and bit PF0DDR.
2. WAIT-A input when the WAITS bit in PFCR4 is 0.
3. SCSO-C input when SCS0S1 and SCS0S0 = B'10 in PFCR5, and SSUMS, MSS,
4. SCSO-C output when SCS0S1 and SCS0S0 = B'10 in PFCR5, and SSUMS, MSS,
EXTRGS = 1
CSS1, and CSS0 = B'00××, B'0101, or B'0110.
CSS1, and CSS0 = B'011×.
