Part Number: AM5746


Hi Sitara support Team,

I would like to make sure about the AL Control register(0x120-0x121).

-ET1100 Datasheet shows
5 Device Identification:
0: No request
1: Device Identification request
15:6 Reserved

-PRU_ICSS_EtherCAT_Slave_Controller_Register_List Wiki site shows
5-15 Reserved
processors.wiki.ti.com/.../PRU_ICSS_EtherCAT_Slave_Controller_Register_List

Is this description in this Wiki site typo?
Could I just refer the register information in ET1100 Datasheet?

Best regards,
Kanae

    Kanae,

    Yes it's a typo and you can refer to the register information in ET1100 Datasheet.

    Bit 5 is checked in ecatslv.c:

    #if EXPLICIT_DEVICE_ID
    /*Evaluate if register 0x120 Bit5 (Request Explicit DeviceID) is set*/
    bExplicitDevIdRequested = ((EscAlControl & (UINT16)STATE_DEVID)>>5);
    #endif

    Regards,

    Garrett
