Port 1  
P1 is an 8-bit bidirectional I/O port with internal pull-ups. P1 provides interrupt capability  
for a keyboard interface.

Port 3  
P3 is an 8-bit bidirectional I/O port with internal pull-ups.  
PROG#  
Programming Pulse input  
The programming pulse is applied to this input for programming the on-chip EPROM/  
OTPROM.

Program Store Enable/Read signal output  
PSEN# is asserted for a memory address range that depends on bits RD0 and RD1 in  
UCONFIG0 byte (see Table 13, Page 15).

P3.7  
Read signal output to external data memory depending on the values of bits RD0 and RD1  
in UCONFIG0 byte (see Table 13, Page 15).  
RST  
Reset input to the chip  
Holding this pin high for 64 oscillator periods while the oscillator is running resets the device.  
The Port pins are driven to their reset conditions when a voltage greater than V  
whether or not the oscillator is running.  
is applied,  
IH1  
This pin has an internal pull-down resistor which allows the device to be reset by connecting  
a capacitor between this pin and VDD.  
Asserting RST when the chip is in Idle mode or Power-Down mode returns the chip to normal  
operation.

P1.6  
RXD sends and receives data in serial I/O mode 0 and receives data in serial I/O modes 1,  
2 and 3.

When I C controller is in slave mode, SCL receives clock from the master controller.  
SPI Serial Clock  
When SPI is in master mode, SCK outputs clock to the slave peripheral. When SPI is in  
slave mode, SCK receives clock from the master controller.

Timer 1:0 External Clock Inputs  
When timer 1:0 operates as a counter, a falling edge on the T1:0 pin increments the count.  
Timer 2 Clock Input/Output  
P1.0  
P1.1  
For the timer 2 capture mode, T2 is the external clock input. For the Timer 2 clock-out mode,  
T2 is the clock output.

I
Timer 2 External Input  
In timer 2 capture mode, a falling edge initiates a capture of the timer 2 registers. In auto-  
reload mode, a falling edge causes the timer 2 register to be reloaded. In the up-down counter  
mode, this signal determines the count direction: 1= up, 0= down.  
O
Transmit Serial Data  
P3.1  
TXD outputs the shift clock in serial I/O mode 0 and transmits data in serial I/O modes 1,  
2 and 3.

Digital Supply Voltage  
Connect this pin to +5V or +3V supply voltage.  
Programming Supply Voltage  
The programming supply voltage is applied to this input for programming the on-chip EPROM/  
OTPROM.
