5.2.1.12.4 Physical configuration of I/O channels
These registers define the function of the channels. Depending on the desired configuration, the following assign-
ments can be made with respect to the existing software and hardware:
•
One physical configuration as input or output
•
An explicit assignment as digital or analog input
•
An explicit assignment of input impedance (only for digital inputs)
•
An explicit assignment as PWM output
•
An explicit assignment as parallel output
5.2.1.12.4.1 Physical configuration
Name:
cfgPinMode01 to cfgPinMode08
cfgPinMode09 to cfgPinMode24
cfgPinMode25 to cfgPinMode32
cfgPinMode33 to cfgPinMode48
These registers configure the function of the channels.
Channels 1 to 8 can only be used as digital inputs.

Channels 25 to 32 can be configured as both digital inputs as well as digital outputs. Parallel connection is possible
when configured as a digital output.
A maximum of 2 adjacent outputs are permitted to be connected in parallel on the outputs (1 main output, 1 parallel
output). In addition, only uneven channel numbers can be main outputs. Parallel connections are not possible via
inputs.

Channels 33 to 48 can be configured as both digital inputs as well as digital outputs. The outputs support PWM.
Parallel connection is possible when configured as a digital output. A parallel connection is only possible with
adjacent outputs. This approach begins with the pin with the smallest number.
