Prototype
procedure Expander_Set_PullUpsPortA(ModuleAddress: byte; Data_:
byte);
byte);
Returns
Nothing.
Description
The function sets Port Expander's PortA pull up/down resistors.
Parameters :
-
ModuleAddress
: Port Expander hardware address, see schematic at the bot
tom of this page
-
Data_
: data for choosing pull up/down resistors configuration. Each bit corre
sponds to the appropriate pin of the PortA register. Set bit enables pull-up for
corresponding pin.

Requires
Port Expander must be initialized. See Expander_Init.
Example
// Set Port Expander's PORTA pull-up resistors
Expander_Set_PullUpsPortA(0, 0xFF);
