N/A
Description:
This register indicates the current operating state of fiber-optic links A and B. The lower
byte (bits O-7) indicates the actual link status while the upper byte (bits 8-15) shows whether the
communication taking place is synchronized or not.
l
If the lower byte is equal to (xx01 H), the UDC module is waiting for a request from the PMI for an
operating system.
l
If the lower byte is equal to (xx02H), the UDC module is downloading an operating system to the
PMI.
l
If the lower byte is equal to (xx03H), the UDC module and the PMI are exchanging data.
l
If the lower byte is equal to (xx06H), the external loopback test is being conducted on the fiber-optic
link.
l
If the upper byte is equal to (01xxH), the communication between the UDC module and the PMI is
synchronized.
l
If the upper byte is equal to (02xxH), the communication between the UDC module and the PMI is
unsynchronized.
