1. The level of output pulse turn into the level when the pulse output starts by writing the TRAMR
Pulse output mode is mode to count the count source internally generated and outputs the pulse which inverts
the polarity from the TRAIO pin each time the timer underflows (see Table 14.3 Pulse Output Mode
Specifications).

written to the reload register and counter (refer to 14.1.1.1 Timer Write
Control during Count Operation).
The TEDGSEL bit in the TRAIOC register can select the polarity level when
the pulse output starts
The pulse which inverts the polarity of the TRAIO output can be output from
the TRAO pin (selected by the TOENA bit in the TRAIOC register)
The pulse output from the TRAIO pin can be stopped by the TOPCR bit.
P1_7 or P1_5 is selected by the TIOSEL bit in the TRAIOC register.
