CHAPTER 4 I/O PORTS

Port 7 pull-up setting register (PUL7)

The bits of the pull-up setting register correspond to the pins of port 7 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 4.7-2 shows the pull-up resistor settings assigned to the values of the bits of the port 7 pull-up
register.
