Subclock (Jp: 1, 2) - Fujitsu SK-96650_6A0_380-120PMC User Manual

3.4 Subclock (JP: 1, 2)

All MB9600 microcontrollers and all MB96300 derivates with ordering post-sign „W‟ like e.g.
MB96F38xRW support a 32 kHz sub-clock (X0A, X1A), other devices like e.g. MB96F38xRS
do not support a sub-clock but will offer additional port-pins (e.g. P04_0, P04_1) instead.
Please check the related datasheet.
JP1: defines usage of pin 69 (X1A)
JP2: defines usage of pin 68 (X0A)

Setting Description
1-4 Pin 68 is connected to the 32 kHz sub-clock (X0A)
2-4 Pin 68 is used as port pin P04_0
Pin 68 is connected to GND (in case that subclock-
3-4
device is used, but no 32 kHz crystal is connected)
1-2 Pin 69 is connected to the 32 kHz sub-clock (X1A)
2-3 Pin 69 is used as port pin P04_1
