MOTOR CONTROLLER (Cont’d)
10.6.10 PWM Generator Block
The PWM generator block produces three inde-
pendent PWM signals based on a single carrier
frequency with individually adjustable duty cycles.
Depending on the motor driving method, one or
three of these signals may be redirected to the oth-
er functional blocks of the motor control peripheral,
using the PCN bit in the MDTG register.
When driving PM BLDC motors in six-step mode
(voltage mode only, either sensored or sensor-
less) a single PWM signal (Phase U) is used to
supply the Input Stage, PWM and Channel Man-
ager blocks according to the selected modes.
For other kind of motors requiring independent
PWM control for each of the three phases, all
PWM signals (Phases U, V and W) are directed to
the channel manager, in which deadtime or a high
