Hello,
I try to use PIN57 as an digital input, but it doesn't work. I've connected a pulldown resistor to it, and with a hardwired key I can make this input high. When i just startup the board (my own software is not running) PIN57 becomes high after a while, without the key is pressed.
I've set the pin as IO and as input by these commands:
reg open \Drivers\BuiltIn\DigitalIO
reg set value UseAsIOA DWORD 0x5A03E30C
reg set value DataDirA DWORD 0x10004304
reg set value DataInitA DWORD 0x00000000
reg set value IRQCfg0A DWORD 0x00000000
reg set value IRQCfg1A DWORD 0x00000000
reg set value IRQCfg2A DWORD 0x00000000
reg set value UseAsIOB DWORD 0x00000000
reg set value DataDirB DWORD 0x00000000
reg set value DataInitB DWORD 0x00000000
reg set value IRQCfg0B DWORD 0x00000000
reg set value IRQCfg1B DWORD 0x00000000
reg set value IRQCfg2B DWORD 0x00000000
reg set value UseAsIOC DWORD 0x00000F40
reg set value DataDirC DWORD 0x00000F40
reg set value DataInitC DWORD 0x00000000
reg set value IRQCfg0C DWORD 0x00000000
reg set value IRQCfg1C DWORD 0x00000000
reg set value IRQCfg2C DWORD 0x00000000
reg set value UseAsIOD DWORD 0x00000000
reg set value DataDirD DWORD 0x00000000
reg set value DataInitD DWORD 0x00000000
reg set value IRQCfg0D DWORD 0x00000000
reg set value IRQCfg1D DWORD 0x00000000
reg set value IRQCfg2D DWORD 0x00000000
reg open \Drivers\BuiltIn
reg open \Drivers\BuiltIn\CF
reg set value Flags DWORD 0x04
reg open \Drivers\BuiltIn
reg save
What triggers this pin to become high?
