CHAPTER 4 I/O PORTS
● Port 6 pull-up setting register (PUL6)
The bits of the pull-up setting register correspond to the pins of port 6 in one-to-one correspondence.
When the pull-up resistor is selected by using the pull-up setting register, the pin will be at "H" level
(pull-up state) instead of Hi-Z during stop (SPL = 1). During a reset, however, the pull-up is invalid and
the pin remains at Hi-Z.
Figure 4.6-2 shows the pull-up resistor settings assigned to the values of the bits of the port 6 pull-up
setting register.
