Pin Function
P83DDR
Pin Function
P85/IRQ4/RxD1
The pin function is switched as shown below according to the combination of the RE bit in
SCR of SCI_1 and the P85DDR bit.
P84/IRQ3/TxD1
The pin function is switched as shown below according to the combination of the TE bit in
SCR of SCI_1 and the P84DDR bit.
P83/LPCPD *
The pin function is switched as shown below according to the P83DDR bit.
* When the IRQ4E bit in IER is set to 1, this pin is used as the IRQ4 input pin.
* When the IRQ3E bit in IER is set to 1, this pin is used as the IRQ3 input pin.
2. Not supported by the H8S/2148B and H8S/2145B (5-V version).
LPCPD input pin. The LPCPD input pin can only be used in mode 2 or 3 (EXPE = 0).
