Accessing GPIO_WK0 on OMAP4430 blaze

Other Parts Discussed in Thread: 4430

Hi All, 

Im working on a device whose interrupt line is connected to 
gpio_wk0(SIM_IO/gpio_wk0/SAFE MODE) on omap4430 blaze platform, from 
the TRM i learnt that this gpio line is shared between gpio_wk0 and 
gpio_0 and configured by setting proper mux config in 

CONTROL_CORE_PAD0_KPD_COL1_PAD1_KPD_COL2 - for gpio 0 
CONTROL_WKUP_PAD0_GPIO_WK0_PAD1_GPIO_WK1 - for gpio_wk0 

But the TRM pad config register entry for the gpio_wk0 pin has 
following options 
mode 0: reserved 
mode3 : gpio_wk0 
mode6 : hw_dbg1 
as opposed to what is mentioned in the schematics. If i configure the 
gpio line using "SIM_IO" entry its not being properly configured. also 
i cannot find the entry for SIM_IO anywhere in the 4430 TRM, is this a 
known issue? How do i properly access the gpio_wk0? 

Kindly help. 

Thanks,
