Center-Aligned PWM
When TPMxCnVH:L = TPMxMODH:L
When TPMxCnVH:L = (TPMxMODH:L - 1)
TPMxCnVH:L is changed from 0x0000 to a non-zero value
TPMxCnVH:L is changed from a non-zero value to 0x0000

You can write to the Channel Value register (TPMxCnV) when the timer is not in input capture
mode for TPMV2, not TPMV3.

Update the TPMxCnVH:L
registers with the value of
their write buffer after both
bytes are written and when
the TPM counter changes
from (TPMxMODH:L - 1) to
(TPMxMODH:L).
Note: If the TPM counter is a
free-running counter, then
this update is made when the
TPM counter changes from
0xFFFE to 0xFFFF.
Produces 100% duty cycle.
Produces a near 100% duty
cycle.
Waits for the start of a new
PWM period to begin using
the new duty cycle setting.
Finishes the current PWM
period using the old duty
cycle setting.
Clears the write coherency
mechanism of
TPMxMODH:L registers.

Produces 0% duty cycle.
Produces 0% duty cycle.
Changes the channel output at
the middle of the current PWM
period (when the count
reaches 0x0000).
Finishes the current PWM
period using the new duty
cycle setting.
Does not clear the write
coherency mechanism.
