Addresses Description
T32CP Other Types
DT90038 DT9038 Work 2 for F96 (SRC) instruction
The position of the first matching data, counting from the starting 16-bit area, is
stored here when an F96 (SRC) instruction is executed.
DT90039 to
DT90043 DT9039 to
DT9043 Not used
DT90044 DT9044 High-speed counter elapsed value for ch0
The elapsed value (24–bit data) for the high–speed counter is stored here. Each time
DT90045 DT9045
the ED instruction is executed, the elapsed value for the high–speed counter is auto-
matically transferred to the special registers DT9044 and DT9045.
The value can be written by executing a DMV (F1) instruction.
DT90046 DT9046 High-speed counter target value for ch0
The target value (24–bit data) of the high–speed counter specified by the high–speed
counter instruction is stored here.
DT90047 DT9047
counter instruction is stored here.
Target values have been preset for the various instructions, to be used when the
high–speed counter related instruction F166 to F170 is executed. These preset val-
ues can only be read, and cannot be written.
DT90048 DT9048 High-speed counter elapsed value area for ch1
The elapsed value (24–bit data) for the high–speed counter is stored here. Each time
DT90049 DT9049
the ED instruction is executed, the elapsed value for the high–speed counter is auto-
matically transferred to the special registers DT9048 and DT9049.
The value can be written by executing a DMV (F1) instruction.
DT90050 DT9050 High-speed counter target value area for ch1
The target value (24–bit data) of the high–speed counter specified by the high–speed
counter instruction is stored here.
DT90051 DT9051
counter instruction is stored here.
Target values have been preset for the various instructions, to be used when the
high–speed counter related instruction F166 to F170 is executed. These preset val-
ues can only be read, and cannot be written.
