Sub Clock (Jp: 36, 37) - Fujitsu SK-96620_350-64PMC(1) User Manual

4.9 Sub Clock (JP: 36, 37)

In contrast to the MB96300 super series the complete MB96600 super series has the sub
clock option. All MB963xx derivates with ordering post-sign „W‟ like e.g. MB96F35xRW
support a 32 kHz sub clock (X0A, X1A). other MB963xx devices like e.g. MB96F35xRS do
not support a sub-clock but will offer additional port-pins (e.g. P04_0, P04_1) instead.
Please check the related datasheet.
JP36: defines usage of Pin 19 (X0A/P04_0)
JP37: defines usage of Pin 20 (X1A/P04_1)

Setting Description
1-2 Pin 19 is connected to the 32kHz sub clock (X0A)
2-4 Pin 19 is used as P04_0
Pin 19 is connected to GND (in case that sub clock-
2-3
device is used, but no 32kHz crystal is connected)
1-2 Pin 20 is connected to the 32kHz sub clock (X1A)
2-3 Pin 20 is used as P04_1
