4.8.1 Register Overview
4.8.2 Timer12 - Related Registers
The generation of the patterns for a 3-channel pulse width modulation (PWM) is based
on timer T12. The registers related to timer T12 can be concurrently updated (with well-
defined conditions) in order to ensure consistency of the three PWM channels.
Timer T12 supports capture and compare modes, which can be independently selected
for the three channels CC60, CC61 and CC62.
Register T12 represents the counting value of timer T12. It can only be written while the
timer T12 is stopped. Write actions while T12 is running are not taken into account.
Register T12 can always be read by SW.
In edge-aligned mode, T12 only counts up, whereas in center-aligned mode, T12 can
count up and down.
