MOTOR CONTROLLER (Cont’d)
Effect on PWM generator: the PWM generator
12-bit counter is reset as soon as CKE = 0; this en-
sures that the PWM signals start properly in all
cases. When these bits are set, all registers with
preload on Update event are transferred to active
registers.
Bit 5 = SR: Sensor ON/OFF.
0: Sensorless mode
1: Position Sensor mode

as there is a write access to the OO[5:0] bits in
MPHST register. In this case, the PWM low/high

register.

Bit 3 = V0C1: Voltage/Current Mode
0: Voltage Mode
1: Current Mode
Bit 2 = SWA: Switched/Autoswitched Mode
0: Switched Mode
1: Autoswitched Mode
Note 1 : after reset, in autoswitched mode (SWA
=1) , the motor control peripheral is waiting for a C
commutation event.
Note 2: After reset, a C event is immediately gen-
erated when CKE and SWA are simultaneaously
set due to a nil value of MCOMP.
Bit 1 = PZ: Protection from parasitic Zero-crossing
event detection
0: Protection disabled
1: Protection enabled
Note: If the PZ bit is set, the Z event filter
(ZEF[3:0] in the MZFR register is ignored.
Bit 0 = DCB: Data Capture bit
0: Use MZPRV (Z
1: Use MZREG (Z
