New page

= Action =

Configures all other features of a Xmega port or port pin like for example pullup but not the data direction.

You still need to use PORTx = state or PINx.y = state to configure the data direction of that port or pin in addition to CONFIG XPIN.

 

 

= Syntax =

CONFIG XPIN=PORT|PIN, INVERTIO=invio, SLEWRATE=slew, OUTPULL=pull, SENSE=sense

 

 

= Remarks =

Normal AVR port pins can be configured as an input or output. When configured as an input (CONFIG PIN=INPUT) they can also be set to tri-state (write a 0 to the PORT register) or to activate the pull up resistor(write a 1 to the PORT register).

The xmega has many more options. The Xmega manual explains all the options.

The CONFIG XPIN statement will set the proper registers.

PORT

PIN

| valign="top" width="100%" style="width: 512px; border: 1px solid rgb(0, 0, 0);" |
The pin to be configured. For example PORTC.0

When configuring the whole port (all the pins must have the same functionality), use PORT. For example : PORTD

INVERTIO

| valign="top" width="100%" style="width: 512px; border: 1px solid rgb(0, 0, 0);" |
This option will invert the data for both input and output modes.

Possible values : ENABLED (will invert data), DISABLED(normal mode)

|- style="vertical-align: top;"

SLEWRATE

| valign="top" width="100%" style="width: 512px; border: 1px solid rgb(0, 0, 0);" |
Will enable or disable the slewrate. Enabling the slew rate will increase the rise/fall time by 50%-150%. Possible values : ENABLED, DISABLED

|- style="vertical-align: top;"
| valign="top" width="15%" style="width: 88px; border: 1px solid rgb(0, 0, 0);" |
OUTPULL

| valign="top" width="100%" style="width: 512px; border: 1px solid rgb(0, 0, 0);" |
Sets the output or pull mode. The following options are available:

- TOTEM : output totem pole

- BUSKEEPER : output totem pole, input bus keeper

- PULLDOWN : output totem pole, input pull down

- PULLUP : output totem pole, input pull up

- WIREDOR : output wired OR

- WIREDAND: output wired AND

-WIREDORPULL : output wired OR, input pull down

-WIREDANDPULL : output wired AND, input pull up

|- style="vertical-align: top;"
| valign="top" width="15%" style="width: 88px; border: 1px solid rgb(0, 0, 0);" |
SENSE

| valign="top" width="100%" style="width: 512px; border: 1px solid rgb(0, 0, 0);" |
In input mode, the trigger sense can be configured. Possible values :

- BOTH : sense both edges

- RISING : sense rising edge

-FALLING : sense falling edge

-LOW_LEVEL  :sense low level

- INP_DISABLED : digital input buffer disabled (only PORTA-PORTF)

</div>
 

Normal AVR code that use : PORTX.Y=1  to activate the pul up, should be written as : CONFIG XPIN=PORTX.Y,OUTPULL=PULLUP

Config Porte.5 = Input
Config Xpin = Porte.5 , Outpull = Pullup , Sense = Falling 'enable Pull up and reaction on falling edge

$Crystal = 32000000 '32MHz

Config Xpin = Portc.0 , Slewrate = Enabled , Outpull = Buskeeper , Sense = Low_level
Config Xpin = Portc.1 , Slewrate = Enabled , Outpull = Buskeeper , Sense = Low_level

'setup the whole port at once
Config Xpin = Portd , Slewrate = Enabled , Outpull = Buskeeper , Sense = Low_level
