Testing outputs
Sub menu items of the menu 5.2 allows testing of the output drivers (if enabled).
You can select the outputs (menu item 5.2.1 to 5.2.4) to toggle on/off.
When an output is off it will show the following:
VOLT OFF
12.4
OUTPUT 1
VOLT is the current voltage being read back from the pin, OFF shows that the output is currently turned off. When you turn on the output, reading on the VOLT output should go down to zero.
The use of this test overrides any of the configurations with regards to whether these pins are set as outputs or not.
