4.1.4 Power-Up/Halt
If the device is powered-down, this command will power-up the device. When powered-on, no computations will be
running. If the part is already powered-on, all computations will be halted.
4.1.5 Power-Down and Software Reset
The device has two power-down states to conserve power. If the chip is put in stand-by state, all circuitry except the
analog/digital clock generators is turned off. In the sleep state, all circuitry except the digital clock generator and the
instruction decoder is turned off. Waking up the CS5550 out of sleep state requires more time than out of stand-by
state, because of the extra time needed to re-start and re-stabilize the analog clock signal.
4.1.6 Calibration
The device has the capability of performing a system offset calibration and gain calibration. Offset and gain calibra-
tions should NOT be performed at the same time (must do one after the other). Proper inputs must be supplied to
the device before initiating calibration.

00 = Software Reset
01 = Halt and enter stand-by power saving state. This state allows quick power-on time
10 = Halt and enter sleep power saving state. This state requires a slow power-on time
