Register Definitions
controlling the respective relays are written to or the card is
reset. The card remains in the busy state until both timers have
timed out.
• Read Only
• Undefined bits readback as all 1s
• BUSY~: 0 = Busy, 1 = Ready
Current Sense Select (W) Base + 3
h
This register controls the current sense relays of the card. Since
only one current sense channel at a time per slot is allowed,
these channel selects are encoded. This allows for none or one
current sense relay to be selected. Writing to this register starts
the reed relay timer.
• Write Only
• Undefined bits are not used
Valid current sense selection values are: 00001

- corresponds to current sense select on channel 2.
01101

- no current sense relays selected.
(Example: Setting the current sense register to 00110

selects
channel six. Therefore relays K11 and K12 would be closed.)
