I/O Port (attached with a pullup resistor)
Figure PORT-2 Port block attached with a pullup resistor
Notes :
Pullup resistor control register (PCR) R/W
Controls turning the pullup resistor on/off.
0 : Pullup resistor disabled
1 : Pullup resistor enabled
In stop mode priority is also given to the setting of the pullup resistor control register.
This function is not available when a relevant pin is in use as an external bus pin. Do not write “1” to this register.
