DEVICE CONFIGURATION

The ADIS16365 SPI provides device configuration control as

well, eight bits at a time. Each function has a configurable

Figure 3, the first byte contains the write bit and register

address. For example, the first byte of a write to the SMPL_PRD

is 0x80 (write bit high) plus 0x36 (low-byte address), which is

0xB6. The second byte of the DIN sequence contains the data,

which loads into the specified location. For the lowest sample

rate setting, 0xFF is the code. The entire DIN sequence for

setting the slowest sample rate is 0xB6FF.

Many of the configuration registers have also been assigned

mirror locations in the flash memory, which effectively provides

them with a backup storage function. To assure the backup of

these registers, the COMMAND register provides an initiation

bit for manual flash updates. The ENDURANCE register

provides a running count of these events.

BURST MODE DATA COLLECTION

Burst mode data collection offers a more process-efficient

method for collecting data from the ADIS16365. In 12 sequen-

tial data cycles, separated by only one SCLK time period, all 11-

output registers clock out on DOUT. In Figure 4, this sequence

starts when the DIN sequence is 0x3E00. After that, the

contents of each output register, comes out of DOUT, starting

with SUPPLY_OUT and ending with AUX_ADC. The

addressing sequence determines the order of the outputs in

burst mode.
