1. By writing to the TRAMR register, the output pulse is set to the level when the pulse output starts.
In pulse output mode, an internally generated count source is counted, and a pulse with inverted polarity is
output from the TRAIO pin each time the timer underflows (refer to Table 17.3).

are written to the reload register and counter (refer to 17.3.2 Timer Write
Control during Count Operation ).
The level when the pulse output starts is selected by the TEDGSEL bit in
the TRAIOC register.
Pulses inverted from the TRAIO output polarity can be output from the TRAO pin
(selectable by the TOENA bit in the TRAIOC register).
Output from the TRAIO pin is stopped by the TOPCR bit in the TRAIOC register.
Use of the TRAIO pin is selected by bits TRAIOSEL0 and TRAIOSEL1 in the
TRASR register.
