Data Sheet
W66910 PCI ISDN S/T-Controller
Publication Release Date:
Feb,2001
Revision 1.0
-46 -
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.
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, 3 Reserved
These bits are reserved. The write values are don't care, but are read as zero.
8.1.5 Timer 1 Register
Value after reset : 00H

T1MD
CNT6
T1MD Timer1 Mode
0 = Single mode: The timer counts once and generates a T1EXP interrupt when expires.
1 = Periodical mode: The timer counts periodically and generates an interrupt at each expiration.
CNT6-0 Count Value
The expiration time is defined as:
T1 = CNT[6:0] * 0.1 second
