List Command
list_jump_cond
Function Conditional (absolute) list jump: This command executes the command
list_jump_pos(
Pos ), if the current IOvalue at the EXTENSION 1 connector’s 16-bit digital
input port 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 ). Otherwise, the
directly following list command will be immediately executed.
Call list_jump_cond( Mask1, Mask0, Pos )
Parameters Mask1,
Mask0
16-bit masks as unsigned 32-bit values
(only the least significant 16 bits are evaluated)
Pos absolute jump address [0 … (2
20
–1)] as an unsigned 32-bit value
Comments • The command is synonymous with the list_jump_pos_cond command (see comments
there).

5 essentially unchanged functionality, however:
• extended range of
Pos values
• Jumps into or out from the protected buffer area (“List 3”) are not allowed (illegal jump
commands will be ignored during processing, also see list_jump_pos).
