Set bits TPSC2 to TPSC0 in 16TCR to
select the counter clock source. If an
external clock source is selected, set
bits CKEG1 and CKEG0 in 16TCR to
select the desired edge(s) of the
external clock signal.
Set bits CCLR1 and CCLR0 in 16TCR
to select the counter clear source.
Set the time at which the PWM
waveform should go to 1 in GRA.
Set the time at which the PWM
waveform should go to 0 in GRB.
Set the PWM bit in TMDR to select
PWM mode. When PWM mode is
selected, regardless of the TIOR
contents, GRA and GRB become
output compare registers specifying
the times at which the PWM output
goes to 1 and 0. The TIOCA pin
automatically becomes the PWM
output pin. The TIOCB pin conforms
to the settings of bits IOB1 and IOB0
in TIOR. If TIOCB output is not
desired, clear both IOB1 and IOB0 to 0.
Set the STR bit to 1 in TSTR to start
the timer counter.
