Ctrl Command set_extstartpos
Function defines the start address (within the range of “List 1” or “List 2”) where execution should
continue upon subsequent external list starts.
Call
set_extstartpos( Pos )
Parameter
Pos
absolute address of the first list command to be executed as an unsigned
32-bit value; allowed range: [0 … (2
20
–1)]
Comments • By default, an external list start results in a continuation or start at the beginning of
“List 1” (
Pos
= 0).
•
Pos
must be within the range of “List 1” or “List 2”. Otherwise,
Pos
= 0 will be set.
• The specified start address will be used for all subsequent external list starts until a new
address is specified via set_extstartpos or set_extstartpos_list . An address range
validity check is performed on
Pos
before each external list start;
Pos
might therefore
become set to 0 at a later point (and remain at this value) if the configuration was corre-
spondingly changed in the meantime (see
config_list ).
• Also see "External List Start", page 210 .
