GPIO EINT13, EINT14 Pull-up seems not working

Hi,

I need a help to resolve the Interrupt handling in the mini2440 ( s3c2440);

I have configured the GPIO  GPG port pins 19 and 20  ( CON4 pins) as
Interrupt pins ( EINT13 and EINT14 ) ; developed a driver in kernel space
similar to the example mini2440_buttons.c

I have set the Pull-up for these Pins as OFF by using hte built it routine
s3c24xx_setpull(port, 1); IT seems this pull up function doesn't work.

but when I turn on the board and run this driver, ( open the Test
application using this driver). these EINT13 and EINT14 pins goes HIGH
always.

My external interrupts are driving Active HIGH, so I wanted to configure
these EINTx pins as ZERO/low  by default. 
Please help me to set these EINTx pins to ZERO ( or to disable the Pull
up).
thanks in advance,
sampath

I don't how fast you want to be able to control these pins.  If speed is
not a factor I would suggest reading section 8.4.1 GPIO Usage example in
the Pengutronix Quickstart guide.

Thanks Dave.
But my requirements is to use Interrupts.

I realized that, when this Pin is configured for Interrupts, it should be
either Puled Up or Pulled Down. not sure.

Just trying to work through this myself:

EINT12 [18:16] Setting the signaling method of the EINT12.
000 = Low level      001 = High level        01x = Falling edge triggered
10x = Rising edge triggered                     11x = Both edge triggered


You want the port to start off low then cause an interrupt when the port
goes high.  So, the signalling method is set to 001 (high level) or 10x
(rising edge triggered).

When the uP boots up the ports are in their reset state which is a high
pull-up on.  Correct?  

Could you just put a pull-down resistor on the port and then let up the
interrupt source pull it high?

Interested in the outcome.
