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)
