Created page with "= Action = Sets the port or a port pin to the right data direction. Action =

Sets the port or a port pin to the right data direction.

 

 

= Syntax =

CONFIG PORTx = state

CONFIG PINx.y = state

state

| valign="top" width="100%" style="width: 465px; border: 1px solid rgb(0, 0, 0);" |
A numeric constant that can be INPUT or OUTPUT.

 

INPUT will set the data direction register to input for port X.

OUTPUT will set the data direction to output for port X.

You can also use a number for state. &B00001111, will set the upper nibble to input and the lower nibble to output.

 

You can also set a single port pin with the CONFIG PIN = state, statement.

Again, you can use INPUT, OUTPUT or a number. In this case the number can be only zero or one.

|- style="vertical-align: top;"
| valign="top" width="17%" style="width: 93px; border: 1px solid rgb(0, 0, 0);" |
x

| valign="top" width="100%" style="width: 465px; border: 1px solid rgb(0, 0, 0);" |
A valid port letter such as A,B,C etc.

Example : CONFIG PORTB = Output

|- style="vertical-align: top;"
| valign="top" width="17%" style="width: 93px; border: 1px solid rgb(0, 0, 0);" |
y

| valign="top" width="100%" style="width: 465px; border: 1px solid rgb(0, 0, 0);" |
A valid pin number in the range of 0-7.

Example : CONFIG PINB.0=INPUT

|}
</div>
 

The best way to set the data direction for more than 1 pin, is to use the CONFIG PORT, statement and not multiple lines with CONFIG PIN statements.

 

You may not use variables for the port letters and pin numbers. If you need to dynamically set a pin direction, you can use this form : SET PORTB.somepin , where somepin may be a constant or a variable.

If the the port itself is also dynamic, then you could use OUT with the proper address.
