4.14.2
The PWM module has a total of two internal outputs to control the Low Side Outputs, the High Side Outputs and / or the PTB2
output with pulse width modulation. See
Section 4.18, “General Purpose I/O - PTB[0…2]
4.14.2.1
Die 2 Die Interface Clock.
4.14.2.2
This signal serves as waveform output of PWM channel 1.
4.14.2.3
This signal serves as waveform output of PWM channel 0.
4.14.3
This section describes in detail all the registers and register bits in the PWM module. Reserved bits within a register will always
read as 0 and the write will be unimplemented. Unimplemented functions are indicated by shading the bit.

(81)
Based on the D2D clock speed, the PWM8B2C module is capable of generating PWM signal
frequencies higher than the maximum output frequency of the connected driver (HS, LS).
Please refer to
Do not exceed the driver maximum output frequency!
