WORD MONITOR END OF BLOCK OPTIONS
Address: 20
End of block A options - Stop, Repeat, Go Alternate.
Interrupt at end of block A.
End of block B options - Stop, Repeat, Go Alternate.
Interrupt at end of block B.

CONFIGURATION REGISTER 3
Address: 21
Enable tag word option.
Enable time tag option.
Enable time tag command syncs only option.

WORD MONITOR EXAMPLE
Setting up and Implementing the WORD monitor!
Set address of data block in BLOCK A/ B REG.
Set end of data block address in BLOCK A/ B END REG.
Set end of DATA BLOCK options in REG 20.
Select end of block interrupt in REG 20.
Select tag word option in REG 21.
Select time tag option in REG 21.
Select word monitor in REG 9.
Start monitor in REG 9.
The monitor now collects data until the end of block address is reached. The address of the last
word in the block is stored in the Last Word Address register, the selected End- of- Block option is
executed and an end of block interrupt is issued if enabled in reg 20.
The CPU can now read the entire data block and use the Tag Words and the Time Tags to
analyze the data.
8.4.0
SIMULTANEOUS MONITOR AND REMOTE TERMINAL
The ET can operate as a simultaneous monitor and remote terminal. This mode is activated by
setting bits 8 and 9 of Configuration register 1 to a "1". In this mode the ET will respond as a
remote terminal to the address set in the Basic Status register. This address is set either by the
hardwire address or software.
The ET will respond to all addresses except that in the Basic Status register as a monitor, word
monitor or message monitor depending on the monitor mode selected. In the message monitor
mode, the ET will only respond to terminal addresses which have not been masked in registers
22 and 26.
When the ET receives a message with the address in the Basic Status register, it will become a
fully operational Remote Terminal for that message.
8.4.1
SIMULTANEOUS MODE INTERRUPT HANDLING
In this dual mode of operation, all the interrupts for the Remote terminal and Monitor operation
remain valid; therefore both RT and MT messages can set interrupts and push headers on the
FIFO during the dual mode operation.
