3.9User Push Buttons INT0, INT1, INT2 and ICU0/TIN0

There are four user push buttons on the starter kit, which can be connected to the microcontroller.

JP92 – JP95 Connects the user push buttons (SW2 – SW5) to the microcontroller

Jumper	Setting	Description
JP92 (SW2)	ON (closed)	Button INT0 is connected to the microcontroller
	OFF (open)	No connection to the microcontroller
JP93 (SW3)	ON (closed)	Button INT1 is connected to the microcontroller
	OFF (open)	No connection to the microcontroller
JP94 (SW4)	ON (closed)	Button INT2 is connected to the microcontroller
	OFF (open)	No connection to the microcontroller
JP95 (SW5)	ON (closed)	Button ICU0/TIN0 is connected to the microcontroller
	OFF (open)	No connection to the microcontroller

Default: grey

3.10 User DIP Switch 8 Bit (S4)

There is an 8 bit user-DIP-switch on-board, which can be connected to one MCU port (P26), Connecting High- or Low level to the pins. S3, also an 8 bit DIP-switch, dis-/connect the eight channels of S4 to the MCU pins. In case of other usage of these pins, open S3 switch accordingly.

DIP switch		Setting	Logical value
S4/1 - 8		ON (closed)	0 (low)
		OFF (open)	1 (high)
Default:
	grey
Table 3-20: S4 Values

Note:

DIP-switch S3 is used to connect DIP-switch S4 to the MCU port pins at port P26.

DIP switch	Setting	Description
S3/1 - 8	ON (closed)	S4/1-8 connected to MCU port P26_0-7
	OFF (open)	No connection to the microcontroller

Default: grey
