FUNCTIONS
PB0
PB1
PB2
ADCK / PC0
VREF / PC1
INPUT/OUTPUT 3-bit Input / Output PORTB.
INPUT/OUTPUT Selects a terminal circuit for each port from the following
INPUT/OUTPUT by the mask option.
•C-MOS Schmitt Trigger Input Terminal with Pull-up
Resistance (ISP)
•C-MOS Schmitt Trigger Input Terminal (IS)
•C-MOS Output Terminal (OC)
When the ports are selected as the input terminal, PB0
operates also as RESTART signal input terminal to return
from STANDBY mode, and PB1 operates also as the Edge
Detector Terminal.
INPUT
