OUTPUT_FLOAT()

Syntax:	output_float (pin)
Parameters:	Pins are defined in the devices .h file.  The actual value is a bit address.  For example, port a (byte 5) bit 3 would have a value of 5*8+3 or 43.  This is defined as follows: #define PIN_A3 43
Returns:	undefined
Function:	Sets the specified pin to the input mode. This will allow the pin to float high to represent a high on an open collector type of connection.
