HARDWARE MODE
The hardware mode is intended for applications that do not have an external controller available or do not
require the extended features offered by the serial port. Tying the SPS pin to VSS disables the serial port,
clears all internal register bits and maps the IPD, U/ A , and CP/ EX bits for both channels to external bits.
(See Table 3.) In the hardware mode, both the input and output time slots default to time slot 0.

0 = Expand
1 = Compress
8 / A4
AS0/AS1/AS2
(Channel X & Y)
Algorithm Select (see Table 5)
9 / A5
U/ A
(Channel Y)
Channel Y Data Format
0 = A-law
1 =
-law
18 / SDI
IPD
(Channel Y)
Channel Y Idle Select
0 = Channel active
1 = Channel idle
19 / CS
IPD
(Channel X)
Channel X Idle Select
0 = Channel active
1 = Channel idle
NOTES:
1. SCLK must be tied to VSS when the hardware mode is selected.
2. When both channels are idled, power consumption is significantly reduced.
3. The NIL will power-up within 800 ms after either channel is returned to active from an idle state.
