Bit 7 = DG:Debug Option.
This bit is used to enter debug mode. As a result,
C, D and Z events are output on 2 pins MCDEM
and MCZEM in Switched and Autoswitched mode,
C and U events are output in Speed Measurement
mode. Refer to
more details
0: Normal mode
1: Debug mode
Bit 6 = PWMW: PWM W output control
0: PWM on Compare Register W is not output on
1: PWM on Compare Register W is output on
Bit 5 = PWMV: PWM V output control
0: PWM on Compare Register V is not output on
1: PWM on Compare Register V is output on MCP-
