The conversions on the single Setup (MC = 0) or multiple Setups (MC =
1) are continuously performed.
The RC bit is used in conjunction with the LP bit when the LP bit is set to
logic 1. If LP = 0, the RC bit is ignored. If LP = 1, the ADC waits for user to
read data conversion(s) before converting again. The RC bit is ignored
during calibrations. Refer to Calibration Protocol for details.
number of CSR’s to be accessed (0000=1). They are also used to deter-
mine how many Setups are converted when MC=1 and a command byte
with its MSB = 1 is issued. Note that the CS5522 has two CSRS, the
CS5524 has four CSRs, and the CS5528 has 8 CSRs.
Sleep Mode (Oscillator inactive).
For PD = 1, the CPD pin goes to a Hi-Z output state.
Power Save.
Reduced Power Mode
Activate a Reset cycle. To return to Normal Operation write bit to zero.
No reset has occurred or bit has been cleared (read only).
Bit is set after a Valid Reset has occurred. (Cleared when read.)
Bit is set when an oscillatory condition is detected in the modulator.
Bit is set when input signal is more positive than the positive full scale,
more negative than zero (unipolar mode), or when the input is more neg-
ative than the negative full scale (bipolar mode).
