MOTOR CONTROLLER (Cont’d)
Note on using the 3 MCIx pins as standard
I/Os: When none of the MCIx pins are needed in
the application (for instance when driving an in-
duction motor in open loop), they can be used as
standard I/O ports, by configuring the Motor Con-
Table 36. MCIx pin configuration summary
*When PCN=0, TES=0 SR=0, inputs in OFF-state are put in HiZ or grounded depending on the value of
the DISS bit in the MSCR register.
Notes:
1. Analog input: Based on analog comparator and analog voltage reference. The corresponding digital
I/O is disabled and data in the DR register is not representative of data on the input.
2. Digital input: Use of standard V
