6.3.10 Timer output register m (TOm)
The TOm register is a buffer register of timer output of each channel.
The value of each bit in this register is output from the timer output pin (TOmn) of each channel.
The TOmn bit oh this register can be rewritten by software only when timer output is disabled (TOEmn = 0). When
timer output is enabled (TOEmn = 1), rewriting this register by software is ignored, and the value is changed only by the
timer operation.
To use the P00/TI00, P01/TO00, P16/TI01/TO01, P31/TI03/TO03, P42/TI04/TO04, P05/TI05/TO05, P06/TI06/TO06,
P41/TI07/TO07 pin as a port function pin, set the corresponding TOmn bit to “0”.
The TOm register can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of the TOm register can be set with an 8-bit memory manipulation instruction with TOmL.
Reset signal generation clears this register to 0000H.
