i.MX6 DualLite reference manual errors

PLE — Tue, 01 Jun 2021 13:30:48 GMT

Dear Support Team,

I found some errors in the i.MX 6DualLite Reference Manual concerning clock gating.
Document Number: IMX6SDLRM
Rev. 5, 05/2020

In Table 18-3 System Clocks, Gating, and Override, for USDHCn the table refers to CCGR5 for "Module Clock Gating Enable".
But looking at Chapter "18.6.28 CCM Clock Gating Register 5 (CCM_CCGR5)" in "CCM_CCGR5 field descriptions", there is no fields for USDHCn.
In fact, looking at Chapter "18.6.29 CCM Clock Gating Register 6 (CCM_CCGR6)", the fields seems to be coherent with Table 18-3 indexes.
So it's look like Table 18-3 must be change to refer to CCM_CCGR6 insteed of CCM_CCGR5.

In the following chapters, the descriptions refers to 8 CGR registers for clock gating but only 7 (CCM_CCGR0 to CCM_CCGR6) are documented in the Reference Manual.
18.6.24 CCM Clock Gating Register 1 (CCM_CCGR1)
18.6.25 CCM Clock Gating Register 2 (CCM_CCGR2)
18.6.26 CCM Clock Gating Register 3 (CCM_CCGR3)
18.6.27 CCM Clock Gating Register 4 (CCM_CCGR4)
18.6.28 CCM Clock Gating Register 5 (CCM_CCGR5)
18.6.29 CCM Clock Gating Register 6 (CCM_CCGR6)
Only Chapter "18.6.23 CCM Clock Gating Register 0 (CCM_CCGR0)" mentions 7 CGR registers.

Can you report this to the Documentation Team in order to provide a new revision of this Reference Manual ?

Best Regards,

Thanks for your reporting this document error.

1) Yes, you are right. refer to CCM_CCGR6, not CCM_CCGR5

2) "There are 8 CGR" is a typo. There are only 7 CGR.

I will report this to the team. Thanks.
