Notes: If the TMO pin is used for remote control sending, a careless timer output
pulse may be output when the remote control mode is set after the output
has been switched to the TMO output. Perform the switching and setting in
the following order.
[1] Set the remote control mode.
[2] Set the TMJ-1 and 2 counter data of the timer J.
[3] Switch the P37/TMO pin to the TMO output pin.
[4] Set the ST bit to 1.
