8.3 Using the Pull-up or Pull-down selection jumper for pins 2-9.
Jumper allows to change the input configuration for 2-9. Using the Pull-up or Pull-down
selection jumper for pins 2-9 the input voltage is pulled through a 4.7Kohm resistor to up
or down in this way:
1-2: PULL-DOWN 2-3: PULL-UP
8.4 Using the Pull-up or Pull-down selection jumper for pins 10, 11,
12, 13 and 15.
Jumper allows to change the input configuration for pins 10, 11, 12, 13 and 15. Using
the Pull-up or Pull-down selection jumpers for those pins will pull them up or down
through a 4.7Kohm resistor:
1-2: PULL-DOWN 2-3: PULL-UP
