12.13 EtherCAT CSR and Process Data RAM Access Registers (Directly Addressable)

This section details the directly addressable System CSRs, outside of the EtherCAT Core, which are related to the Eth-

erCAT Core. For information on how to access EtherCAT registers, refer to Section 12.11, "EtherCAT CSR and Process

Data RAM Access," on page 208. The EtherCAT Core registers are detailed in Section 12.14, "EtherCAT Core CSR

Registers (Indirectly Addressable)," on page 223.
