io-pullup
Command io-pullup
Arguments f | g [enable | disable]
Security
Level
2 (data)
Device Type All
Default N/A
Description Enables or disables the internal pull-up resistor on indicated GPIO port dynamically without restarting
the module.
The command requires two parameters the first identifies the GPIO port and bit to be configured the
second determines the state of the internal pull-up resistor, for example:
io-pullup f1 enable : Enables the internal pull up resistor for the f port first bit.
io-pullup g7 disable : Disables the internal pull-up resistor for the g port seventh bit.
The effects of this command are temporary and will not be persistent across a restart. If the state of
the pull-up resistor is required to persist across a power cycle or a restart use the io-pullup-f and
io-pullup-g
commands.
Port assignment and exceptions:
f0 Read (POST output) g0 Read or Write
f1 Read or Write g1 Read or Write
f2 Read (RF_LINK output) g2 Read or Write
f3 Read (WLN_CFG output) g3 N/A
f4 Read or Write g4 N/A
f5 Read or Write g5 N/A
f6 Read (LED_CON output) g6 Read or Write
f7 Read or Write g7 Read or Write
When the LED signal has not been disabled those bits indicated as LED Outputs can only be read in
order to determine the state of the LED output (See WLNN DP500 Family Databook for details). To
disable the LED‟s use one of the following commands post-led, rf-link-led, wln-cfg-led and
conn-led
.
Any attempt to set an unavailable port or configure a port to an illegal state will be ignored.
