12.14 EtherCAT Core CSR Registers (Indirectly Addressable)

This section details the indirectly addressable EtherCAT Core CSRs, which are accessed via the directly addressable

EtherCAT CSR Interface Data Register (ECAT_CSR_DATA) and EtherCAT CSR Interface Command Register

(ECAT_CSR_CMD). For information on how to access EtherCAT registers, refer to Section 12.11, "EtherCAT CSR and

Process Data RAM Access," on page 208. The directly addressable EtherCAT registers are detailed in Section 12.13,

"EtherCAT CSR and Process Data RAM Access Registers (Directly Addressable)," on page 214.

Note:

For EtherCAT Core CSR registers longer than one byte, the LSB has the lowest address and the MSB the

highest address.

The read/write behavior of specific EtherCAT Core register bits may differ depending on how the register

is accessed. Each EtherCAT Core register includes “ECAT Type” and “PDI Type” columns, which provide

the bit/field type for register accesses via an EtherCAT Master Node or Process Data Interface (SPI / Host

Bus), respectively.
