These can be buffered to drive the transducer or used as synchronizing signals for a transducer
drive circuit. BX1 and BX2 are 0 to +5V signals.
DRDY goes low every 81,920 cycles of XIN (when in read conversion data mode) to indicate
that new data has been placed in the output port. DRDY goes high when all the serial port data
is clocked out, when the serial port is being updated with new data, when a calibration is in
progress, or when the device is in SLEEP.
Data from the serial port will be output from this pin at a rate determined by SCLK . The data
will either be conversion data, or, calibration values, dependent upon the command word that
has been previously input on the SID pin. The SOD pin furnishes a high impedance output
state when not transmitting data (SMODE = 0).
