5.3.2 Digital Inputs and Outputs
After power-up of the device all 4 connection groups are configured as inputs;
this corresponds to the instruction
CONF_DIO(0)
. The following table shows
how the inputs and outputs (IN, OUT) are configured when you use the value
of the first column as instruction argument.
Please pay attention to the following restriction:
Only if the inputs/outputs are configured with
CONF_DIO(12)
(see pin assign-
menton page 14) will you be able to fully access the inputs/outputs with the
instructions
DIGOUT_WORD
,
SET_DIGOUT
,
CLEAR_DIGOUT
,
DIGIN_WORD
,
DIGIN
.
For any other configuration you have to read out or write into the corresponding
hardware register (see instructions
PEEK
and
POKE
in the
ADbasic
manual).
