Initial Settings: In the operating modes, there are five registers that require initialization.
Make the following register settings before setting the operating mode with bits MD1 and MD0 in
the timer mode register (TMDR).
Set the timer period buffer register (TPBR) to 1/2 the PWM carrier period, set dead time Td in the
timer dead time data register (TDDR) (when outputting an ideal waveform, Td = H'0000), and set
{TPBR value + 2Td} in the timer period data register (TPDR).
Set {PWM duty initial value – Td} in the free write operation addresses for TBRU to TBRW.
The values of TBRU to TBRW should always be set in the range H'0000 to H'FFFF – 2Td, and the
value of TPBR should always be set in the range H'0000 to H'FFFF – 4Td.
