Type Description
UART function

Receive data input
Input/Output function
I/O
P3.0 is a bi-directional I/O port with internal pull-ups.
Reset configuration
I
Input (high level)
UART function
O Transmit data output
OE active at low or high level depending of PMSOEN bits in SIOCON Reg.
Input/Output function
I/O
P3.1 is a bi-directional I/O port with internal pull-ups.
Reset configuration
Z
High impedance due to PMOS switched OFF
External interrupt 0
I INT0 input set IE0 in the TCON register. If bit IT0 in this register is set, bits IE0
are set by a falling edge on INT0. If bit IT0 is cleared, bits IE0 is set by a low
level on INT0.
Input/Output function
I/O
P3.2 is a bi-directional I/O port with internal pull-ups.
Timer 0: Gate input
I INT0 serves as external run control for Timer 0 when
selected in TCON register.
Reset configuration
I
Input (high level)
External Interrupt 1
I INT1 input set OEIT in ISEL Register, IE1 in the TCON register.
If bit IT1 in this register is set, bits OEIT and IE1 are set by a falling edge on
INT1. If bit IT1 is cleared, bits OEIT and IE1 is set by a low level on INT1
UART function
Output enable. A low or high level (depending OELEV bit in
I
ISEL Register) on this pin disables the PMOS transistors of TxD
(P3.1) and T0 (P3.4). This function can be disabled by software
Input/Output function
I/O
P3.3 is a bi-directional I/O port with internal pull-ups.
Timer 1 function: Gate input
I INT1 serves as external run control for Timer 1 when
selected in TCON register.
Reset configuration
I
Input (high level)
UART function
O OE active at low or high level depending of PMSOEN
bits in SIOCON Reg.
