Pin Description, continued
SYMBOL TYPE
DESCRIPTIONS
PORT 3: Port 3 is a bi-directional I/O port with internal pull-ups. All bits have
alternate functions, which are described below:
RXD(P3.0) : Serial Port 0 input
TXD(P3.1) : Serial Port 0 output
INT0 (P3.2) : External Interrupt 0
P3.0 − P3.7 I/O INT1(P3.3) : External Interrupt 1
T0(P3.4) : Timer 0 External Input
T1(P3.5) : Timer 1 External Input
WR (P3.6) : External Data Memory Write Strobe
RD (P3.7) : External Data Memory Read Strobe
PORT 4: Port 4 is a 4-bit bi-directional I/O port. The P4.0 also provides the
P4.0 − P4.3 I/O alternate function WAIT which is the wait state control signal. The P4.3 also
provides the alternate function REBOOT which is H/W reboot from LD flash.
* Note: TYPE I : input, O: output, I/O: bi-directional.
