I (P1.5)
Port 1:
Port 1 is a 6-bit I/O port with user-configurable outputs. During reset Port 1
latches are configured in the input only mode with the internal pull-up disabled. The
operation of the inputs and outputs depends upon the port configuration selected.
Refer to
Section 9.12.1 “Port configurations”
and
Table 13 “DC electrical
characteristics”
for details. P1.2 is an open drain when used as an output. P1.5 is
input only.
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described below:
P1.0 —
Port 1 bit 0
TxD —
Serial port transmitter data.
P1.1 —
Port 1 bit 0
RxD —
Serial port receiver data.
P1.2 —
Port 1 bit 2. (Open drain when used as an output.)
T0 —
Timer/counter 0 external count input, overflow output, or PWM output.
SCL —
I
2
C-bus serial clock input/output.
P1.3 —
Port 1 bit 2. (Open drain when used as an output.)
INT0 —
External interrupt 0 input.
SDA —
I
2
C-bus serial data input/output.
P1.4 —
Port 1 bit 2.
INT1 —
External interrupt 1input.
P1.5 —
Port 1 bit 5. (Input only.)
RST —
External Reset input during power-on or if selected via UCFG1. When
functioning as a reset input a LOW on this pin resets the microcontroller, causing I/O
ports and peripherals to take on their default states, and the processor begins
execution at address 0.
When using an oscillator frequency above 12 MHz, the
reset input function of P1.5 must be enabled. An external circuit is required to
hold the device in reset at power-up until V
DD
has reached its specified level.
When system power is removed V
DD
will fall below the minimum specified
operating voltage. When using an oscillator frequency above 12 MHz, in some
applications, an external brownout detect circuit may be required to hold the
device in reset when V
DD
falls below the minimum specified operating voltage.
Also used during a power-on sequence to force In-System Programming mode.
Ground:
0 V reference.
Power Supply:
This is the power supply voltage for normal operation as well as Idle
and Power-down modes.
