2 Register Map Overview

The DS160PRxx 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 channel register set and can be configured independent of each other.

Both Share and Channel registers of a single channel bank are contained within a single register page as shown in Table 2-1.
