H8S/2456, H8S/2456R, H8S/2454 Group
• PF0/WAIT-A/ADTRG0-B/SCS0-C/OE-A (H8S/2454 Group)
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, bit OEE in DRAMCR, bits MSS,
CSS1, and CSS0 in SSCRH and bit SSUMS in SSCRL of SSU, bits TRGS1, TRGS0, and
EXTRGS in ADCR_0 of ADC, bit OES in PFCR2, bits ADTRG0S and WAITS in PFCR4,
bits SCS0S1 and SCS0S0 in PFCR5, and bit PF0DDR.
• Modes 1, 2, and 4 Modes 3 and 7 (EXPE = 1)
