NAME
Digital I/O, Type C Port 2; LCD Segment-Driver Output. This port functions as either
bidirectional I/O or alternate LCD segment-drive outputs. The reset condition of the port is with
all bits at logic 1. In this state, a weak pullup holds the port high. This condition serves as an
input mode. The port pins also contain a Schmitt voltage input. Setting the PCF2 bit switches
all pins on this port to LCD segment-drive outputs.
Digital I/O, Type C Port 3; LCD Segment-Driver Output. This port functions as either
bidirectional I/O or alternate LCD segment-drive outputs. The reset condition of the port is with
all bits at logic 1. In this state, a weak pullup holds the port high. This condition serves as an
input mode. The port pins also contain a Schmitt voltage input. Setting the PCF3 bit switches
all pins on this port to LCD segment-drive outputs.
Digital I/O, Type-C Port 4; LCD Segment-Driver Output. This port functions as either
bidirectional I/O or alternate LCD segment-drive outputs. The reset condition of the port is with
all bits at logic 1. In this state, a weak pullup holds the port high. This condition serves as an
input mode. The port pins also contain a Schmitt voltage input. Setting the PCF4 bit switches
