8168 McAsp

Other Parts Discussed in Thread: SYSCONFIG

In 8168's datasheet, we can find McAsp's PWRIDLE SYSCOFIG register, its address offset is 04. But I cannot find this register in 8168 manual. Why?

Thanks

    Hi Chen,

    I will check with our McASP design engineers about that register. If this register is not integrated inside the DM816x McASP module, we will remove it from the DM816x Datasheet (sprs614c). If this register is integrated inside the DM816x McASP module, we will add it in the DM816x TRM (sprugx8a).

    If this register is integrated inside the DM816x McASP module, it will match the description and offset (0x4) of the OMAP4430 ES2.x MCASP_SYSCONFIG register:

    Description   Power idle configuration register.

    Bits           Field Name     Description                                          Type     Reset

    31:2          RESERVED    Reserved                                                R          0x0

    1:0            IDLE_MODE    0x0: Force-idle mode                             RW       0x2

                                              0x1: No-Idle mode                                  

                                              0x2: Smart-idle mode - default state

                                              0x3: Reserved

    As I can read the McASP2 SYSCONFIG register reset value (at address 0x48050004) successfully, I read the value of 0x00000002 in my own DM816x EVM, most probably this register will be added in the DM816x McASP TRM. I will let know our final decision.

    Regards,
