HCCV Registers
Each of the 32 HDLC channels has a 7-bit command vector that resides in the
corresponding address of the command RAM. The structure of a command vector is as
follows:
Note: Accesses to these registers are possible only if register bit HCR:DSPCTRL = 1

Indication for a B-channel. HDLC protocol is performed on all 8
data bits
Indication for a D-channel. HDLC protocol is performed only on
the 2 MSB data bit in the Receive Input Buffer and Transmit
Output Buffer
Normal operation
Reset the HDLC receiver
End transmission
Start transmission at the first bit of the D-channel
Start transmission at the second bit of the D-channel
Start transmitting a flag (beginning with the fifth bit of the flag,
since ’0111’ is automatically inserted)
