3.3 Subclock (JP: 1, 2)
Some devices like e.g. MB96F37xRW support a 32 kHz sub-clock (X0A, X1A), other devices
like e.g. MB96F37xRS 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)

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
