Section 8 I/O Ports
8.5
8.5.1
Port 4 is an 8-bit I/O port. Port 4 pins also function as 14-bit PWM output pins (PWX1, PWX0),
8-bit timer 0 and 1 (TMR0, TMR1) I/O pins (TMCI0, TMRI0, TMO0, TMCI1, TMRI1, TMO1),
timer connection I/O pins (CSYNCI, HSYNCI, HSYNCO) (H8S/2148 Group only), SCI2 I/O pins
(TxD2, RxD2, SCK2), IrDA interface I/O pins (IrTxD, IrRxD), host interface output pins
(HIRQ12, HIRQ1, HIRQ11) (H8S/2148 Group and H8S/2147N only), and the IIC1 I/O pin
(SDA1) (option in H8S/2148 Group and H8S/2147N only). Port 4 pin functions are the same in all
operating modes.
Figure 8.12 shows the port 4 pin configuration.
