Writing to the Registers

Channel Enable
Register
Appendix B
A read of the Channel Enable register (base + 08
regardless of the channel states.
You can write to the following Form C Switch registers:
Status/Control register (base + 04
Channel Enable register (base + 08
The only write allowed to the Status/Control register (base + 04
0. Writing a "1" to bit 0 resets the switch (all channels open) You must then
write a "0" to bit 0 to complete the reset.
Note
All relays are latching and will remain in the last state during power-down
and power-up unless a reset occurs. A reset connects all channel common
(C) terminals to the corresponding normally closed (NC) terminals. Any
combination of channel open or closed states is allowed.
Writes to the Channel Enable register (base + 08
close the desired channel (see Figure B-1). For example, write a "1" to bit 2
of the Channel Enable register to close channel 02. Or, write a "0" to bit 14
of the register to open channel 14.
