OMAPL138 PCLKCR1?

Other Parts Discussed in Thread: OMAP-L138

Page 234 of SPRS586A discusses clock enable bits for the eCAP:

"The clock enable bits (ECAP1/2/3/4ENCLK) in the PCLKCR1 register are used to turn off the eCAP
modules individually (for low power operation). Upon reset, ECAP1ENCLK, ECAP2ENCLK,
ECAP3ENCLK, and ECAP4EN CLK are set to low, indicating that the peripheral clock is off."

Where is the PCLKCR1 register that this page references?

    Indeed, this register appears to be missing from our documentation altogether. I am checking with the product group to see if they can point me in the right direction.

    Hunter,

    I apologize for the delay, but as you can imagine it is tough to get everything done in a timely manner during the holidays. In any case I finally have an answer for you:

    This register does not exist in the C6748/6/2 or the OMAP-L138. I think it somehow got copied over from the c28x datasheet http://focus.ti.com/lit/ds/symlink/tms320f2808.pdf (Pg47 has the description) over to the C674x/OMAP-L138 datasheets as they use the same eCAP IP block.

    If you want to gate the module clocks of the eCAP modules, the equivalent functionality is provided via the power sleep controller (PSC, LPSC20).
