7.6.1 Register Types: Global, Shared, and Channel

The DS280BR810 has 3 types of registers:

  1. Global Registers - These registers can be accessed at any time and are used to select between individual channel registers and shared registers, or to read back the TI ID and version information.
  2. Shared Registers - These registers are used for device-level configuration, status read back or control. Set register 0xFF[0] = 0 and configure 0xFF[5:4] to access the shared registers.
  3. Channel Registers – These registers are used to control and configure specific features for each individual channel. All channels have the same channel register set and can be configured independent of each other. Set register 0xFF[0] = 1 and configure register 0xFC to access the desired channel register set.

Refer to the Programming Guide for additional information on register configuration.
