Control during Count Operation).
n: Value set in TRAPRE register, m: Value set in TRA register
The TEDGSEL bit in the TRAIOC register selects the level at the start of
pulse output.
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.
P1_7 or P1_5 is selected by the TIOSEL bit in the TRAIOC register.
