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 proto-
cols 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 11-8: LED CONFIGURATION
Exec data Tag bytes identify data streams sent from the Exec block back to the host
software.
Description
Mode
M = CFG[7:6]
State
S = CFG[5]
Time
T = CFG[4:0]
Set immediate 00 1 = On, 0 = Off N/A
Blink once – On or Off 10 1 = On, 0 = Off T + 1 units
Blink continuous 11 Initial state: 1 = On, 0 = Off T + 1 units
Reserved 01
Legend: Time “unit” = 50 ms
Note: Set LED to blink continuously, on/off time = 100 ms.
CFG = 0xC1 (M = b’11’, S = 0, T = 1)
