Undelayed set_io_cond_list
Short
List Command
Function sets the bits of the 16-bit digital output port on the EXTENSION 1 connector that are set
in the parameter MaskSet, if the current IOvalue at the 16-bit digital input port on the
EXTENSION 1 connector meets the following condition:
((IOvalue AND Mask1) = Mask1) AND (((not IOvalue) AND Mask0) = Mask0)
(i.e. if the bits specified in Mask1 are 1 and the bits specified in Mask0 are 0).
Call
set_io_cond_list( Mask1, Mask0, MaskSet )
Parameters
Mask1,
Mask0,
MaskSet
Comments • The command sets only those bits of the digital output port that are set in the
parameter MaskSet and leaves the other bits unchanged.
• Also see section
Execution", page
Examples • set bit #4 of the output port (DIGITAL OUT4), if bit #0 of the input port (DIGITAL IN0)
(Pascal) is set and bits #1 to #3 (DIGITAL IN1...3) of the input port are not set:
set_io_cond_list($0001, $000E, $0010)
• always set bit #15 of the output port (and leave the other bits unchanged):
set_io_cond_list(0, 0, $8000)
