REGISTER SUMMARY

The AD7616 has six read/write registers used for configuring the device in software mode and an additional 32 sequencer stack registers

for programming the flexible on-chip sequencer and a read only status register. Table 19 shows an overview of the read/write registers

available on the AD7616. The status register is an additional read only register than contains information on the channel pair previously

converted and the CRC result.
