Delay Register - Read and Write

ADDR

Plug-In LA+0x202

 

 

This register is used to set the time that the plug-in module will hold the Board

 

 

Busy signal active. The Board Busy signal is set every time the plug-in receives a

 

 

Write to a relevant Relay Register memory space. The Board Busy signal will be

 

 

removed at the end of the time out that is set by the value contained in this register.

 

 

For each count loaded into this register, the Board Busy signal will be held active

D15-D0

Data Bus

for 1 µs. The delay may be set from 0 to approximately 65 ms, thus accommodating

a wide variation in test station requirements.

16 Bit

 

 

 

 

The Board Busy signal may be monitored by the user, in either a polled or an

 

 

interrupt fashion, and is to be used as an indication that the relays in the newly

 

 

actuated path have settled. Alternatively, the Board Busy signal may also be used to

 

 

drive the TTL Trigger Bus. See the Board Busy, Interrupt Control and Busy

 

 

Trigger Control Register descriptions in the A16 address space.
