The P3PINCFG register controls I/O access to
UART0, the I2C interface, capture compare
input0 and 1, Timer 0 and Timer 1 inputs as well
as defines the direction of P3 when used as
general purpose I/O

Using General Purpose I/O Ports
The VMX51C1020’s 28 I/Os are grouped into
four ports. For each port an SFR register
location is defined. Those registers are bit
addressable providing the ability to control the
I/O lines individually.
When the port pin configuration register value
defines the pin as an output, the value written
into the port register will be reflected at the pin
level.
Reading the I/O pin configured as input is done
by reading the contents of its associated port
register.

When the Port is configured as an
output, setting a port pin to 1 will
make the corresponding pin to
output logic high.
When set to 0, the corresponding
pin will set a logic low.

The following example demonstrates the configuration of the VMX51C1020 I/Os.

//This example continuously reads the P0 and writes its contents into //P1 and it
toggle P2 and P3.

// Configure all P0 as Input
//Configure P1 as Output
//Configure P2 as Output
//Configure P3 as Output

//Write P0 into P1
//Toggle P2 & P3
Port1.0-P1.3 can be used as standard digital
outputs. However, in order to do this, the Timer
