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,
