Note
Quadrature / sinusoidal encoders can be wired (except for the index C
channel) and processed simultaneously with serial encoders.
Pins #5, 6, 13, and 14 of the encoder feedback connectors (X1 – X8) share multiple functions: only one of
these functions (per channel) can be used – configured in software – at one time:
Hall sensors inputs (default configuration).
Pulse and direction PFM output signals (software configuration using Flag D output, OutFlagD).
Serial encoder inputs (software configuration enabling serial encoder line, SerialEncEna).
Quadrature encoder inputs (serial encoder enable line must be 0).
Alternate Sinusoidal encoder inputs (with sinusoidal encoder option).
Note
Each channel is independent of the other channels and can have its
own use for these pins.
Configuring a serial encoder requires the programming of two essential structure elements, and the enabling
of the serial encoder line:
The Serial Encoder Control word,
PowerBrick[].SerialEncCtrl
The Serial Encoder Command word,
PowerBrick[].Chan[].SerialEncCmd
PowerBrick[].Chan[].SerialEncEna = 1
These structure elements must be initialized and can be placed in the startup file of the IDE application
project under Configuration.
