Port mode register 3 (PMR3) controls switching of each pin function of port 3. The switching is
specified in a unit of bit.
PMR3 is an 8-bit read/write enable register. When reset, PMR3 is initialized to H'00.
If the
&6 input pin is set, the pin level need be set to the high or low level regardless of the
active mode and low power consumption mode. Note that the pin level must not reach an
intermediate level.
Bit 7: P37/TMO Pin Switching (PMR37)
PMR37 sets whether the P37/TMO pin is used as a P37 I/O pin or a TMO pin for the timer J
