MOTOR CONTROLLER (Cont’d)
Three kinds of interrupt can be generated in
Speed Sensor Mode, as summarized in
104:
– C interrupt, when a capture event occurs; this in-
– RPI/RMI interrupts occur when the ST[3:0] bits of
– S interrupt occurs when a Speed Error happens
These interrupts may be masked individually.

terrupt shares resources (Mask bit and Flag) with
the Commutation event in Switched/Au-
toswitched Mode, as these modes are mutually
exclusive.
the MPSR register are changed, either automat-
ically or by hardware.
(i.e. a successful comparison between
[MTIM:MTIML] and [MDREG:FF]). This interrupt
has the same channel as the Emergency Stop in-
terrupt (MCES), as it also warns the user about
abnormal system operation. The respective Flag
bits have to be tested in the interrupt service rou-
tine to differentiate Speed Errors from Emergen-
cy Stop events.

Measurement Mode: In order to set-up the
[MTIM:MTIML] counter properly before any speed
measurement, the following procedure must be
applied:
– The peripheral clock must be disabled (resetting
– MTIM, MTIML must be reset and appropriate val-
Note on MTIML: The Least Significant Byte of the
counter (MTIML) is not used when working in Po-
sition Sensor or Sensorless Modes.
Debug option: a signal reflecting the capture
events may be output on a standard I/O port for de-
bugging purposes. Refer to
