IDLE
Note: In the receive direction, the only function of the command vector is to indicate
6.2.5.4
HCSV Registers
Reading a channel from the Receive Output Buffer and Writing to a channel in the
Transmit Input Buffer is done according to the channel’s status vector in the Transmit
Output Buffer. This vector contains 7 flags:
Note: Accesses to these registers are possible only if register bit HCR:DSPCTRL = 1
NO
CRC
STOP
Preliminary Data Sheet
whether the channel is a D-channel or a B-channel, and whether to use CRC
decoding or not.
The main function of the command vector is to control the flow of time slots in the
transmit direction.

Normal operation
The last bits of a message have not filled an octet (8 bits)
