6.3.12 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.
Due to pin arrangement, when using the pins shared by TImn and TOmn as port pins, set the corresponding TOmn bit
to “0”.
The TOm register can be set by a 16-bit memory manipulation instruction.
Set the lower 8 bits of the TOm register with an 8-bit memory manipulation instruction with TOmL.
Reset signal generation clears this register to 0000H.
