MODE CODES
All mode codes applicable to dual redundant
systems are recognized by the CT2566. Mode
codes can be illegalized by the 1553 BC or
RTU device. Refer to the CT2565 or CT2512
data sheets for more information.
* The Stack Pointer is loaded into an internal Address
Register upon receipt of a Controller Start command. This
location is overwritten by data once monitor operation
begins.
