5.RAS Functions
126 PROSEC T2N
(4) Sampling trace function
Collects data from specified devices/registers when the sampling
conditions set by the programmer are realized, and stores it in the
sampling buffer. Also, the number of sampling data may be selected:
• 3 registers + 8 devices ... 2048 times
‚ 7 registers + 8 devices ... 1024 times
The evaluation of the sampling trace conditions and the data collection are
executed at the bottom of the scan.
The sampling data read by the programmer can be displayed in timing charts.
(5) Status latch function
Transfers specified device/register data in batches to the latch data store
area when the latch conditions set by the programmer are realised or when
the latch instruction is run.
The latch conditions are evaluated and data collected at the bottom of the
scan. However, when the latch instruction is run, the data is collected
when the instruction is executed. Latched data can be displayed on the
programmer.
The sampling buffer size setting is not needed in the T2N.
The T2N has built-in sampling buffer (8K words).
