Register Name:
Register Description: Channelized Layer 1 DS0 Data Register
Register Address:
Note: Bits that are underlined are read only, all other bits are read-write.
Note: In normal device operation, the Host must never write to the C[n]DAT[j] registers.
Bits 0 to 7 / Receive DS0 Data (RDATA). This register holds the most current DS0 byte received. It is
used by the transmit side Layer One State Machine when Channelized Network LoopBack (CNLB) is
enabled.
Bits 8 to 15 / Transmit DS0 Data (TDATA). This register holds the most current DS0 byte transmitted.
It is used by the receive side Layer One State Machine when Channelized Local LoopBack (CLLB) is
enabled.
Register Name:
Register Description: Receive Layer 1 Configuration Register
Register Address:
Note: Bits that are underlined are read only, all other bits are read-write.
Bits 0 to 7 / Receive Channel Number (RCH#). The CPU will load the number of the HDLC channel
associated with this particular DS0 channel. If the port is running in an unchannelized mode (RUEN = 1),
then the HDLC Channel Number only needs to be loaded into R[n]CFG0. If the Fast (52 Mbps) HDLC
Engine is enabled on Port 0, then HDLC Channel 1 is assigned to it and likewise HDLC Channel 2 will
be assigned to the Fast HDLC Engine on Port 2 if it is enabled. Hence, these HDLC channel numbers
should not be used if the Fast HDLC Engines are enabled.

00000000 (00h) = HDLC Channel Number 1 (also used for the Fast HDLC Engine on Port 0)
00000001 (01h) = HDLC Channel Number 2 (also used for the Fast HDLC Engine on Port 1)
00000010 (02h) = HDLC Channel Number 3
11111111 (FFh) = HDLC Channel Number 256
