DS26324 3.3V, 16-Channel, E1/T1/J1 Short-Haul Line Interface Unit
6 REGISTER MAPS AND DEFINITION
Six address bits are used to control the settings of the registers. In the parallel nonmultiplexed mode address [5:0]
is used. In multiplexed mode AD[5:0] is used and A[6:1] is used in the serial mode. The register space contains two
independent sets of registers. The lower set of registers (LIUs 1–8) is located from address 00 hex to 1F hex and
contains controls for LIUs 1–8. The upper set of registers (LIUs 9–16) is a duplicate of the lower set, located from
address 20 hex to 3F hex that controls LIUs 9–16. Each of these sets of registers consists of four banks: Primary,
Secondary, Individual LIU, and BERT.
The
ADDP
register for the lower set of registers (LIUs 1–8) is located at address 1F hex. This register is used as a
pointer to access the 4 banks of registers in the lower (LIUs 1–8) register set. Similarly, the
ADDP
register for the
upper set of registers (LIUs 9–16) is located at address 3F hex. This register is used as a pointer to access the four
banks of registers in the upper (LIUs 9–16) register set. Setting an
ADDP
register to AA hex will access the
secondary bank of registers, 01 hex will access the Individual LIU bank of registers, 02 hex will access the BERT
bank of registers, and 00 hex (default on power-up) will access the Primary bank of registers. Note that bank
selection for the lower set of registers (LIUs 1–8) is controlled only by the ADDP at 1F hex and that bank selection
for the upper set of registers (LIUs 9–16) is controlled only by the ADDP at 3F hex.
