/*
* FUNCTION
* GPIO_PullenSetup
*
* DESCRIPTION
* This function is to enable or disable the pull up/down of the related GPIO pin.
* You can not decide to pull up or down, it is set inside the chip.
* And, the setting is different from pin by pin.
*
* PARAMETERS
* enable: enable the pull up/down
*
* RETURNS
* None
*
* GLOBALS AFFECTED
