for the MMC controller) and does not operate as GPIO. If the second
function of the pin is selected, "Fb..." is shown instead of "F...".
"I..." indicates that the pin is configured as an interrupt. The
next letter defines the type of interrupt, "r" for rising edge,
"f" for falling edge, "h" for high level, and "l" for low level. If
the pull-up is enabled, ubbctl adds an "R". Finally, it shows the
pin status. E.g., "IfR1" would be an interrupt triggering on the
falling edge, with pull-up enabled, and currently inactive.
ubbctl can run in continuous mode, in which it updates the status
regularly (currently every 200 ms):
