Note
The settings in MD20116 $MC_IGNORE_INHIBIT_ASUP are ineffective, if the read-in
disable in the interrupt routines is ignored through the following configuration:
MD11602 $MN_ASUP_START_MASK (ignore stop conditions for ASUB) Bit 2 = 1
Behavior when the single block processing is set
Via the following channel-specific machine data it can be set for each interrupt signal, whether the assigned
interrupt routines are processed without interruption despite a set single block processing or whether the single
block processing is to be made active:
MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP
Bit Value Description
In case of a single block processing:
0 • after an activation the interrupt routine is assigned to the interrupt signal 1:
0 the single block processing is effective.
1 the single block processing is suppressed.
1 • after an activation the interrupt routine is assigned to the interrupt signal 2:
0 the single block processing is effective.
1 the single block processing is suppressed.
2 • after an activation the interrupt routine is assigned to the interrupt signal 3:
0 the single block processing is effective.
1 the single block processing is suppressed.
...
Note
MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP is effective only for the single block
processing type 1 (SBL1).
Note
The settings in MD20117 $MC_IGNORE_SINGLEBLOCK_ASUB are ineffective, if the single
block processing in the interrupt routines is ignored through the following configuration:
MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (Prevent single block stop) bit 1 = 1
