Description
Port 0:
Port 0 is an 8-bit I/O port with a user-configurable output type. During reset
Port 0 latches are configured in the input only mode with the internal pull-up disabled.
The operation of Port 0 pins as inputs and outputs depends upon the port
configuration selected. Each port pin is configured independently. Refer to
Section
8.11.1 “Port configurations”
and
Table 7 “DC electrical characteristics”
for details.
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt triggered inputs.
Port 0 also provides various special functions as described below:
P0.0 —
Port 0 bit 0.
CMP2 —
Comparator 2 output.
KBI0 —
Keyboard input 0.
P0.1 —
Port 0 bit 1.
CIN2B —
Comparator 2 positive input B.
KBI1 —
Keyboard input 1.
P0.2 —
Port 0 bit 2.
CIN2A —
Comparator 2 positive input A.
KBI2 —
Keyboard input 2.
P0.3 —
Port 0 bit 3.
CIN1B —
Comparator 1 positive input B.
KBI3 —
Keyboard input 3.
P0.4 —
Port 0 bit 4.
CIN1A —
Comparator 1 positive input A.
KBI4 —
Keyboard input 4.
P0.5 —
Port 0 bit 5.
CMPREF —
Comparator reference (negative) input.
KBI5 —
Keyboard input 5.
P0.6 —
Port 0 bit 6.
CMP1 —
Comparator 1 output.
KBI6 —
Keyboard input 6.
P0.7 —
