• Manufacturer: Maxim Integrated Products, Inc.

MOSCR1: MULTIFRAMES OUT OF SYNC COUNT REGISTER 1
(Address = 25 Hex)
MOSCR2: MULTIFRAMES OUT OF SYNC COUNT REGISTER 2
(Address = 27 Hex)
Note 1: The lower nibble of the counter at address 25 is used by the Path Code Violation Count Register.
Note 2: MOSCR counts either errors in framing bit position (RCR2.0 = 0) or the number of multiframes out of sync (RCR2.0 = 1).
