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

JP2

(X0A)

3-4

Pin 68 is connected to GND (in case that subclock-
device is used, but no 32 kHz crystal is connected)

1-2

Pin 69 is connected to the 32 kHz sub-clock (X1A)

JP1

(X1A)

2-3

Pin 69 is used as port pin P04_1

Default: JP1: 1-2, JP2: 1-4

By default, the 32 kHz sub-clock-crystal is connected to the microcontroller.
