clear_io_cond_list
Function Clears the bits of the 16-bit digital output port on the EXTENSION 1 socket connector that
are set in the parameter MaskClear , if the current IOvalue at the 16-bit digital input port
on the EXTENSION 1 socket connector meets the following condition:
((IOvalue AND Mask1) = Mask1) AND (((not IOvalue) AND Mask0) = Mask0)
(= if the bits specified in Mask1 are 1 and the bits specified in Mask0 are 0 ).
Call clear_io_cond_list( Mask1, Mask0, MaskClear )
Parameters Mask1 16-bit mask.
As an unsigned 32-bit value.
Only the lower 16 bits are evaluated.
Mask0 See Mask1 .
MaskClear See Mask1 .
Comments • clear_io_cond_list clears only those bits of the digital output port that are set in the
parameter MaskClear and leaves the other bits unchanged.
• See also Section ”16-Bit Digital Input Port and 16-Bit Digital Output Port”, page 78 and
Chapter 9.3.2 ”Conditional Command Execution”, page 295.
Examples
(Pascal)
• Clear Bit #4 of the output port (DIGITAL OUT4), if Bit #0 of the input port
(DIGITAL IN0) is set and Bit #1 to Bit #3 (DIGITAL IN1…3) of the input port are not set:
clear_io_cond_list ($0001, $000E, $0010)
• Always clear Bit #15 of the output port (and leave the other bits unchanged):
clear_io_cond_list (0, 0, $8000)
