BURST READ DATA COLLECTION
Burst read data collection is a process-efficient method for collect-
ing data from the ADIS16362. In 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). The addressing sequence shown
in Table 8 determines the order of the outputs in burst read.
OUTPUT DATA REGISTERS
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.
