Function

100pF

4mA

Microcontroller Timer 0 External Input. Input event clock

for timer 0, or GPIO. This pin can also act as GPIO using

the P3 and P3DIR registers.

100pF

4mA

Microcontroller Interrupt 0. When pulled low, INT0 asserts

a microcontroller external interrupt. In addition, if this pin

is pulled low during powerdown this allows the MX51 to

resume executing intructions where it left off. This pin can

also act as GPIO using the P3 and P3DIR registers.

100pF

4mA

Microcontroller Interrupt 1. When pulled low, INT1 asserts

a microcontroller external interrupt. In addition, if this pin

is pulled low during powerdown this allows the MX51 to

resume executing intructions where it left off. This pin can

also act as GPIO using the P3 and P3DIR registers.

100pF

4mA

Microcontroller Standard Serial Interface (Asynchronous)

Output Data. Or GPIO. This pin can also act as GPIO

using the P3 and P3DIR registers.

100pF

4mA

Microcontroller Standard Serial Interface (Asynchronous)

Input Data. Or GPIO. This pin can also act as GPIO using

the P3 and P3DIR registers.

100pF

4mA

Microcontroller General Purpose. This GPIO line can be

configured to be digital input or output by writing to the P1

and P1DIR registers. At reset it is configured as an input

with the output tri-stated.
