Framer Initialization (T1/J1) (cont’d)
Initialization of the HDLC controller (T1/J1)
CRC6 calculation without FS/DL
bits
Automatic synchronization in case of definite framing candidate
(FRS0.FSRF).
In case of multiple framing candidates and CRC6 errors different
resynchronization conditions can be programmed via
FMR2.MCSP/SSP.
Function
HDLC Receiver active, No address comparison
Enable Signaling via time slot 0...31, Interframe Time Fill with
continuous FLAGs
Select interrupts for HDLC processor requests
Select time slot 24 for HDLC data reception and transmission
