Command Description
SET GPIO DIR [IN|OUT] <gpio-
num>
GPIO # = {1|2|3|4|5|6|7|8}
Sets GPIO signal to be an input or an output. The setting
only takes effect if the GPIO signal is not selected for special
function operation. <gpio-num> must be in the range 1-8.
Note: <gpio-num> is 7 for GPIO_9 and 8 for GPIO_10
(GPIO_7 and GPIO_8 are not settable by the user)
NOTE: The direction bit configuration is not changed by a
configuration reset to default.
SHOW GPIO DIR Shows current setting of the GPIO direction configuration.
