SBAS559A May 2022 – December 2022 ADS1285
PRODUCTION DATA
Collectively, the registers contain all the information needed to configure the device (such as data rate, filter mode, specific reference voltage, and so on). The registers are accessed by the read and write commands (RREG and WREG). Registers can be accessed individually, or accessed in multiples given by the number of registers specified in the command field.
Changes made to certain register bits result in a filter reset, thus requiring resynchronization of the ADC. See the Section 8.4.4 section for details.
