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)

Description
1-2
Pin 59 is connected to the 32 kHz sub-clock (X1A)
JP34
(X1A)
2-3
Pin 59 is used as port pin P04_1
1-2
Pin 58 is connected to the 32 kHz sub-clock (X0A)
2-4
Pin 58 is used as port pin P04_0
JP41
(X0A)
2-3
Pin 58 is connected to GND (in case that subclock-
device is used, but no 32 kHz crystal is connected)
Default: JP34: 1-2, JP41: 1-2
By default, the 32 kHz sub-clock-crystal is connected to the microcontroller.
