TAG bytes 0x03, 0x04 and 0x05 write data bytes to their respective script buffers. In
the current architecture, Script Buffer 1 (CBUF1) is used to store communication com-
mands that will be fetched and executed by the COMM block. So, TAG byte 0x03 is
used to delineate data that is to be sent to the script buffer including communication
protocols to be sent to the unit under test. TAG bytes 0x04 and 0x05 are typically not
used. TAG bytes 0x06 and 0x07 configure the LEDs as follows:
TABLE 9-8:
EXEC data TAG bytes identify data streams sent from the EXEC block back to the host
software.
TABLE 9-9:
Set immediate
Blink once – On or Off
Blink continuous
