THEORY OF OPERATION
The ADIS16488A is an autonomous sensorsystem that self
starts when it has a valid power supply. Afterrunning throughits
initialization process, it begins sampling, processing, and
loading calibrated sensordata into the outputregisters, which
are accessibleusingtheSPIport.TheSPIporttypicallyconnects to
a compatible port on an embedded processor, using the connec-
tions as shown in Figure11.
The fourSPIsignalsfacilitatesynchronous, serial datacommuni-
cation. Connect the reset line (RST)to VDD or do not connect
it to anything for normal operation. The factory default
configuration providesuserswith a data readysignal on the
DIO2 pin, which pulses high when new data is available in the
output data registers.

such as the ADIS16488A. Table 8 provides a list of settings
describing the SPI protocol of the ADIS16488A. The initializa-
tion routine of the master processor typically establishesthese
settingsusing firmware commands to write theminto its serial
control registers.

REGISTER STRUCTURE
The register structureand SPIport providea bridge between
the sensor processing system and an external, master processor.
It contains both output data andcontrol registers. The output
data registersincludethelatestsensor data, areal-timeclock, error
flags, alarm flags, and identification data. The control registers
include sample rate, filtering, input/output,alarms, calibration,
and diagnosticconfiguration options. All communication
between the ADIS16488A and an external processorinvolves
either reading or writing to one of the user registers.

Figure 12. Basic Operation
The register structureuses a paged addressing schemethat is
composed of 13 pages, with each pagecontaining 64 register
locations. Each register is 16 bits wide, with each byte having its
own unique addresswithin the memory mapof that page. The
SPI port has access to one page at a time, using the bit sequence
shown in Figure 13.
Select the page to activate for SPIaccess by writing its code to
the PAGE_ID register. Read the PAGE_IDregister to determine
which page is currently active. Table 9 displays the PAGE_ID
contents foreach page,together withtheirbasicfunctions. The
PAGE_ID registeris locatedat Address0x00 on every page.

SPI COMMUNICATION
If the previouscommandwasa read request, theSPIport supports
full duplex communication,which enablesexternal processorsto
write to DIN while reading DOUT (see Figure13). Figure 13
provides a guideline for the bit coding on both DIN and DOUT.
