2 Register Mapping

The DS320PR410 has two types of registers:

  • Share Registers – These registers can be accessed at any time and are used for device-level configuration, status read back, control, or to read back the device ID information.
  • Channel Registers – These registers are used to control and configure specific features for each individual channel. All channels have the same register set and can be configured independent of each other or configured as a group via broadcast writes to bank 0 (channels 0-3).
