RACT Receiver Active
Setting this bit activates the D_ch HDLC receiver. This bit can be read. The receiver must be in
active state in order to receive data.
XACTB Transmitter Active
Resetting this bit activates the D_ch HDLC transmitter. This bit can be read. The transmitter must be
in active state in order to transmit data. Note this bit is active LOW.
PMES PME Trigger Select
0: PCI power management event triggered by D_RMR or D_RME interrupt
1: PCI power management event triggered by layer 1enters F7 state
MFD Multiframe Disable
This bit is used to enable or disable the multiframe structure on S/T interface:
0 : Multiframe is enabled
1 : Multiframe is disabled
DLP Digital Loopback
Setting this bit activates the digital loopback function. The transmitted digital 2B+D channels are
looped to the received 2B+D channels. Note that after hardware reset, the internal clocks will turn off
if the S bus is not connected or if there is no signal on the S bus. In this case, the C/I command ECK
must be issued to enable loopback function.
RLP Remote Loopback
Setting this bit to "1" activates the remote loopback function. The received 2B channels from the S
interface are looped to the transmitted 2B channels of S interface. The D channel is not looped in this
loopback function.
Bits 7, 4 Reserved
These bits are reserved. The write values are don't care, but are read as zero.
