Figure 16.2 Sample Operating Mode Setting Procedure
Set the external pin functions with the pin function
controller (PFC).
Clear the CST bit to 0 in the timer control register
(TCNR) to halt timer counter operation. Make the
operating mode setting while TCNT is halted.
Set 2Td (Td: dead time) in TCNT.
Set dead time Td in the dead time data register
(TDDR), set 1/2 the carrier period in the timer period
buffer register (TPBR), and set {TPBR value + 2Td}
in the timer period data register (TPDR).
Set the output PWM duty cycle {PWM duty cycle
initial value – Td} in the free operation addresses of
the buffer registers (TBRU, TBRV, TBRW).
Set the operating mode in the timer mode register
(TMDR). The PUOA, PUOB, PVOA, PVOB, PWOA,
and PWOB pins are output pins.
Set the CST bit to 1 in TCNR to start the count
operation.
Set the PWM output level with bits OLSN and OLSP
in the timer mode register (TMDR).
