(3) TMPn dedicated I/O control register 0 (TPnIOC0)
The TPnIOC0 register is an 8-bit register that controls the timer output.
This register can be read and written in 8-bit or 1-bit units.
RESET input clears this register to 00H.

and then set the bits again.
2. To enable the timer output, be sure to set the corresponding alternate-function
pins TPnIS3 to TPnIS0 of the TPnIOC1 register to "No edge detection" and
invalidate the capture operation. Then set the corresponding alternate-function
port to output mode.
