41.1 Chip-specific ENC information
41.1.1 ENC Instantiation Information and signal assignment
This device contains one ENC module. The ENC module input signals and output signal
are connected to the XBARA module which provides the capability to drive the ENC
module from external pins or from a Timer. Using timer functions to drive the ENC
inputs can provide a mechanism for customer;s to test the ENC module is functioning
without connected in the intended "incremenatal position sensor" for motor control.
The following table shows how these modules are configured. This adheres to Kinetis K
series FTM instantiations.
