1: The PWM mode is selected via the 00[5:0] bits in the MPHST register, the OE[5:0] bits in
the MPAR register and the OS2 and OS0 bits in the MCRB register as shown in
PWM mode when SR = 1 on page
2: When driving motors with three independent pairs of complementary PWM signals
(PCN = 1), disabling the deadtime generator (DTE = 0) causes the deadtime to be null: high
and low side signals are exactly complemented.
It is therefore recommended not to disable the deadtime generator (it may damage the
power stage), unless deadtimes are inserted externally.
Polarity register (MPOL)
Table 156. MPOL register description
1. This bit always has to be configured whatever the sampling method.
2. Write-once bits; once write-accessed these bits cannot be rewritten unless the processor is reset (see

0: Zero-crossing and End of Demagnetization have opposite edges
1: Zero-crossing and End of Demagnetization have same edge
0: Read the BEMF signal on High channels
1: Read on Low channels
These bits are used together with the OO[5:0] bits in the MPHST register to control
the output channels (see

OP[5:0] bits in the MPOL register must be configured as
required by the application before enabling the MCO[5:0]
outputs with the MOE bit in the MCRA register.
