Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
operating mode, bit WMS1 in WSCR, bit ICE in ICCR of IIC0, and bit P97DDR.
When this pin is set as the P97 output pin in the H8S/2148 Group and
H8S/2147N, it is an NMOS push-pull output. SDA0 is an NMOS open-drain
output, and has direct bus drive capability.
The pin function is switched as shown below according to the combination of
bit EXCLE in LPWRCR and bit P96DDR.
When this pin is used as the EXCL input pin, P96DDR should be cleared to 0.
The pin function is switched as shown below according to the combination of
operating mode, bit IOSE in SYSCR, bit HI12E in SYSCR2, and bit P95DDR.
