13.8.5 RTI types
13.8.5.1 Introduction
All existing RTI types are detailed in the following paragraphs:
Remark: With an 'always active' activating condition, it is not recommended to jump to a label. It does not
make sense because the sequence would continuously jump to that label without executing the
other lines.
13.8.5.2 Bit copy
13.8.5.3 Bit test
Type Type of RTI
Activation condition Activation conditions to change from a non active valid status to a valid status
Executing function Preset functions executed by the RTI when it stands in an active and enable mode
Parameters Function Format
P1 Parameter 1 description Parameter 1 coding format
P2 Parameter 2 description Parameter 2 coding format
P3 Parameter 3 description Parameter 3 coding format
P4 Parameter 4 description Parameter 4 coding format
Type 2
Activation condition Always active
Executing function Copies the register bit defined by P1 in another register bit defined by P2, according to P3 mode.
Parameters Function Format
P1 Bit source Bit description (BD)
P2 Bit destination Bit description (BD)
P3 Mode
0: Normal
1: bit inversion
P4 Not used Not used
Type 3
Activation condition If the test of the bit P1 fulfils the condition requested in P2
Executing function Modification of P3 according to P4 mode
Parameters Function Format
P1 Bit to test Bit description (BD)
P2
Jumps to a label (if existing) and modifies the
bit defined by P3 according to P4
0: Not test
1: Rising edge
2: Falling edge
3: Rising and falling edge
4: state 0
8: state 1
P3 Bit to modify Bit description (BD)
P4 P3 modification mode
0: No modification of P3
1: P3 is set to 1 when jump condition is detected
2: P3 is set to 0 when jump condition is detected
3: P3 is toggled when jump condition is detected
