Double buffer of TRG4 disable.
Stop timer 4.
Set the duty (16 bits).
Set the cycle (16 bits).
Double buffer of TREG4 enable.
(Change the duty and cycle at the interrupt INTTR5.)
Set the mode to invert TFF4 at the match with
TREG4/TREG5, and also set the TFF4 to â0â.
Select the internal clock for the input, and disable the capture
function.
Assign P44 as TO4.
Start timer 4.
