;**Secondary Controls (Fallback)
MD,IDR,35h
;Enable ECTF Fallback: Become the new A Clock master on A
Clock failure,
;synchronizes to a bit clock on local reference 1, but
requires the main divider
;with external input (assumes a CLAD is between the
divider and 4MHzIn).
MI,CKS,IDR
MD,IDR,0FFh
MI,CKMD,IDR
;Move the data to CKS
;Set up Main divider with divide-by-256
;Move the data to divider
;
;**Local Clocks
MD,IDR,0E4h
;Local Selected Clock 3 gets inverted 8.192 MHz, LSC2 gets
2.048 MHz
MI,CK32,IDR
MD,IDR,80h
MI,CK10,IDR
;
;Move it to CK32
;LSC1 is high & LSC0 is low
;Move it to CK10
;*******Set up Local Streams
;
MD,IDR,30h
MI,LBS,IDR
;
;8 Streams at 8 Mbits/s
;Define input streams per IDR
;*******Set up H Bus Streams
;
MD,IDR,0AAh
MI,HSL,IDR
;
;Define H-Bus Streams 0 - 15 for 4 Mbits/s
;Do it
MD,IDR,0FFh
MI,HSH,IDR
;Define H-Bus Streams 16-31 for 8 Mbits/s
;Engage

to start coincident
with the Frame
boundary and Group B
to start halfway through
the Frame. The Groups
operate in normal framing mode
at 8 Mbits/s and are Double Byte wide.
;Note: FRPH sets up the correct routing.
