Signalling for CVMOUTZ and ERROROUTZ
Two red LEDs, LED1 and LED2
are available two indicate a “low” output signal
from CVMOUTZ and ERROROUTZ, respectively.
7.2
Pin Headers for Pull-Down and Pull-Up
A connector CN4 is available to enable easy connection to Voltage1 (3.3V) or
GND via pull-up or pull-down resistances, respectively.
Hereby uneven pins from 1 to 19 (in total ten) are configured as pull-up pin
headers, while the even numbers from 2 to 20 (in total ten) can be used for pull-
down.
By connecting device port pins from CN5
– 8 to CN9 it is therefore possible to
pull a desired port pin to “Low” or “High”.
