PWM MANAGEMENT FOR 3-PHASE BLDC MOTOR DRIVES USING THE ST7MC

Bit 6 = DTE*: Dead Time Generator Enable

0: Disable the Dead Time generator

1: Enable the Dead Time generator and apply complementary PWM signal to the adjacent

switch

Bits 5:0 = DTG[5:0]*: Dead time generator set-up.

These bits set-up the deadtime duration and resolution

* = write once-only bit if PCN bit is set, read/write if PCN bit is reset. To clear the DTE bit if

PCN=1, it is mandatory to clear the PCN bit first.
