This register reads back the card configuration. Card
configuration is determined by the user to distinguish different
load configurations on the same load card type. The default
read back is FF
h
, but you can pull down bits to zero as required
to create a configuration byte unique to the card. (Note that you
can use the mezzanine card registers described below for load
configuration information.) Use the actions

Status & Control (R & W) Base + 2
h
This register reads back the card's status. It also can be used to
reset the board or open all relays (OAR).
Card status is defined as the state of the relay timer. The relay
timer is designed for the armature relays (>4ms). The timer
restarts whenever the registers controlling the respective relays
are written to or the card is reset. The card remains in the busy
state until the timer has timed out.
• Read and Write
• Undefined bits read back as all 1s
• Unused bits for write can be either 0 or 1 (does not matter)
• For BUSY~ (Read Only):
0 = Busy
1 = Ready
• For Reset (Write Only):
0 = no change
1 = causes board reset (non-latched)
