12.14.21 AL STATUS REGISTER
Note 9:
This register is only writable if Device Emulation is off (Device Emulation bit of ESC Configuration Register
is 0). Otherwise, this register will reflect the AL Control Register values. Reading this register from ECAT
clears the AL Status Event bit in the ECAT Event Request Register.
Note:
For EtherCAT Core CSR registers longer than one byte, the LSB has the lowest address and the MSB the
highest address.
