Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 23-22

READ<1:0>:

Address counter increment setting for Read Communication

= Address counter auto-increments, loops on the entire register map

= Address counter auto-increments, loops on register TYPES (DEFAULT)

= Address counter auto-increments, loops on register GROUPS

= Address not incremented, continually reads the same single-register address

bit 21

WRITE:

Address counter increment setting for Write Communication

= Address counter auto-increments and loops on writable part of the register map (DEFAULT)

= Address not incremented, continually writes to the same single register address

bit 20

DR_HIZ:

Data Ready Pin Inactive State Control

= The DR pin state is a logic high when data is NOT ready

= The DR pin state is high-impedance when data is NOT ready (DEFAULT)

bit 19

DR_LINK

Data Ready Link Control

= Data Ready link enabled. Only one pulse is generated on the DR pin for all ADC channels,

corresponding to the data ready pulse of the most lagging ADC.

= Data Ready link disabled. Each ADC produces its own data ready pulse on the DR pin.

bit 18

WIDTH_CRC

Format for CRC-16 on communications

= 32-bit (CRC-16 code is followed by sixteen zeros). This coding is compatible with CRC

implementation in most 32-bit MCUs (including PIC32 MCUs).

= 16 bit (default)

bit 17-16

WIDTH_DATA<1:0>:

ADC Data Format Settings for all ADCs (see Section 5.5 “ADC Output Coding”)

= 32-bit with sign extension

= 32-bit with zeros padding

= 24-bit (default)

= 16-bit (with rounding)

bit 15

EN_CRCCOM:

Enable CRC CRC-16 Checksum on Serial communications

= CRC-16 Checksum is provided at the end of each communication sequence (therefore each

communication is longer). The CRC-16 Message is the complete communication sequence (see

section Section 6.9 “Securing Read Communications Through CRC-16 Checksum” for more

details).

= Disabled (Default)
