2.3 Subclock (JP: 34, 41)
Some devices like e.g. MB96F39xRW support a 32 kHz sub-clock (X0A, X1A), other devices
like e.g. MB96F39xRS do not support a sub-clock but will offer additional port-pins (e.g.
P04_0, P04_1) instead.
Please check the related datasheet.
JP34: defines usage of pin 59 (X1A)
JP41: defines usage of pin 58 (X0A)
