Events:
PIO {reg value} This event is raised
5.27.2 Examples
Setting PIO7 (which lights the PIO7 LED on the evaluation kit if the corresponding switch
is in the LED position) and PIO5 (which is an input pin and thus cannot be set locally by
default):
PIO SET 80 FF (80 in hex is 10000000 in binary, so only the 8th bit is affected; parameters
80 80 etc. would yield the same result)
PIO GET
PIO GET 180 (100 + bits; bit 9, e.g. 100 is always set)
PIO SET 20 FF (try to set 6th bit)
PIO GET
PIO GET 180 (only the 8th direction bit is set by default, so only PIO7 can be set)
PIO GETDIR
PIO GETDIR 80
PIO SETDIR 20 FF
PIO GETDIR
PIO GETDIR a0 (A0 is 10100000 in binary; now both PIO7 and PIO5 can be set)
PIO SET 20 FF
PIO GET
PIO GET 1a0 (now PIO5 is set too)
PIO RESET
PIO GET
PIO GET 100
PIO GETDIR
PIO GETDIR 80
