The default functions of GPIO 4 5, 6 is to control the LED functionality. This default functionality can be
overridden to allow user programmable IO or alternate IO functionality by using the set sys iofunc
<mask> command. Value is entered as a hex number.
The hex value represents a bit mask that controls each bit in the <mask> represents a particular GPIO pin.
If a bit is 0, then that GPIO is driven/read by the firmware per the default function.
The IO function <mask> is encoded as such:
NOTE. Bits 0-3 are mutually exclusive with the bits 4-6. i.e. 0x77 is an illegal value.
If the LEDs are disabled using bits 0, 1, 2 above, you can then use the show i command to read these GPIO.
<2.21> show i
Port=30
For example, to use the alternate functions of the LEDs, the sequence of commands would be:
set sys iofunc 0x70
save
reboot
NOTE: Currently, the alternative GPIO functions are not available in adhoc mode.
