Summary:
Writes a value to the GPIO port.
Description:
Writes the GPIO port.
to write all pins at once instead of one-at-
a-time.
Precondition:
Must have previously been configured as an
output via a ConfigureGPIO call.
Parameters:
portValue - Byte value to set on the port.
Returns:
Function returns true if the transmission is
successful
returns False if there the transmission
fails.

Remarks:
Pins configured for output returns the
current state of the port.
