CONTROL REGISTER A (MCRA)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = MOE: Output Enable bit.
0: Outputs and Clocks disabled
1: Outputs and Clocks enabled
Bit 6 = RST: Reset MTC registers.
Software can set this bit to reset all MTC registers
without resetting the ST7.
0: No MTC register reset
1: Reset all MTC registers
Bit 5 = SR: Sensor ON/OFF.
0: Sensorless mode
1: Sensor mode
Table 29. Sensor Mode Selection
Bit 4 = DAC: Direct Access to phase state register.
0: No Direct Access (reset value). In this mode all
the registers with a preload register are taken
into account at the C event.
1: Direct Access enabled. In this mode, write a val-
ue in the MPHST register to access the outputs
directly. All other registers with a preload regis-
ter are taken into account at the same time.
Table 30. DAC Bit Meaning
Note 1: When the MTC clock is disabled, the
MTIM counter is not reset but as in this case it is in
write access, a reset can be done by software.
Note 2: In direct access mode, only logical levels
(0 or 1) can be output on the MCOx pins. There is
no PWM signal generation in this mode.
Bit 3 = V0C1: Voltage/Current Mode
0: Voltage Mode
1: Current Mode
Bit 2 = SWA: Switched/Autoswitched Mode
0: Switched Mode
1: Autoswitched Mode
Table 31. Switched and Autoswitched Modes
Bit 1 = CFF: Current Feedback Filter
0: Current Feedback Filter disabled
1: Current Feedback Filter enabled
Bit 0 = DCB: Data Capture bit
0: Use MZPRV (ZN-1) for multiplication
1: Use MZREG (ZN) for multiplication
