Table 111. Deadtime generator outputs
1. PWM generation enabled.
As soon as the channels are grouped in pairs, special care has to be taken in configuring
the MPAR register for a PM BLDC drive. If both channels of the same pair are both labelled
‘high’ for example and if the PWM is applied on high channels, the active MCO output x
(OOx = 1 bit in the MPHST register) outputs PWM and the paired MCO output x + 1
(OOx + 1bit in the MPHST register) outputs PWM and vice versa.
When PCN = 0 and a complementary PWM is applied (DTE = 1) on one channel of a pair, if
both channels are active, this corresponds in output to both channels OFF. This is for
security purposes to avoid cross-conduction.
To clear the DTE bit from reset state of MDTG register (FFh), the PCN bit must be cleared
before.

Grouping channels by pairs imposes the external
connections between the MCO outputs and power devices;
the user must therefore pay attention to respect the
