Delay Register - Read and Write

 

ADDR

Plug-In LA+0x102

 

 

 

 

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 for 1μs. The delay may be set from 0 to

 

 

 

 

approximately 65ms, thus accommodating a wide variation in test

 

 

 

 

station requirements.

switches. Writes to the optical multi switch and attenuator

 

 

 

 

 

 

 

 

modules hold the Board Busy signal active until the optical

 

 

 

 

channel has settled.

 

 

 

 

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
