Description
move
16-bit signed integer
The number of TCR1 TPU cycles to
forego (negative) or come after
(positive) the PWM period center
time
$00X6, where X is a number of
Synchronization Signal channel, to
inherit Sync. channel prescaler
or
$0000 to enable direct specification
of prescaler value in prescaler
parameter
presc_addr
16-bit unsigned integer
prescaler
1, 2, 4, 6, 8, 10, 12, 14, ...
The number of PWM periods per
synchronization pulse
– use when apresc_addr = 0
Parameters written by TPU
Other parameters are just for TPU function inner use.
