HARDWARE MODE
The hardware mode is intended for applications that do
not have an external controller available or do not re-
quire the extended features offered by the serial port.
Tying the SPS pin to V
SS
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.

Channel Y Idle Select
0 = Channel active
1 = Channel idle

IPD
(Channel X)
Channel X Idle Select
0 = Channel active
1 = Channel idle
NOTES:
1. SCLK must be tied to V
SS
when the hardware mode is selected.
2. When both channels are idled, power consumption is significantly reduced.
3. The DS2164Q will power-up within 800 ms after either channel is returned to active from an idle state.
