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. Connecting 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 (Table 3). In the hardware mode, both the input and output time slots default to time slot 0.

FUNCTION
Channel X Coding Configuration
0 = Expand
1 = Compress
Algorithm Select (Table 4)
Channel X Data Format
0 = A-law
1 = m-law
Channel Y Coding Configuration
0 = Expand
1 = Compress
Algorithm Select (Table 4)
Channel Y Data Format
0 = A-law
1 = m-law
Channel Y Idle Select
0 = Channel Active
1 = Channel Idle
Channel X Idle Select
0 = Channel Active
1 = Channel Idle
NOTES:
1) SCLK must be connected to VSS when the hardware mode is selected.
2) When both channels are idled, power consumption is significantly reduced.
3) The NIL powers up within 800ms after either channel is returned to active from an idle state.
