BURST READ DATA COLLECTION
Burst read data collection is a process-efficient method for
collecting data from the ADIS16367. In the burst read, all
output registers are clocked out on DOUT, 16 bits at a time, in
sequential data cycles (each separated by one SCLK period). To
start a burst read sequence, set DIN = 0x3E00. The contents of
each output register are then shifted out on DOUT, starting
with SUPPLY_OUT and ending with AUX_ADC (see Figure 13)
according to their address (see Table 8).

Each output data register uses the format in Figure 12 and Table 9.
Figure 6 shows the positive direction for each inertial sensor. The
ND bit is equal to 1 when the register contains unread data. The EA
bit is high when any error/alarm flag in the DIAG_STAT register is
equal to 1.
