Analog PLL Duplicate Registers

dougbailey — Fri, 05 May 2017 19:26:48 GMT

In the iMX6DL reference manual, there are a series of CCM configuration registers for the analog PLL's where the description includes something like:

Address: 20C_8000h base + 0h offset + (4d × i), where i=0d to 3d

I am confused as to what 'i' actually represents.

Are these just duplicate registers i.e. the same register duplicates 4 times?

Is there some intrinsic meaning in the i and that manipulating 0x20c8000 is different from manipulating 0x20c8004?

From all I can tell, these are just duplicates. Can someone tell me otherwise?

Regards

Doug Bailey

Hi Doug

please refer to sect.18.7 CCM Analog Memory Map/Register Definition i.MX6SDL Reference Manual

http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6SDLRM.pdf

Registers _SET,_CLR,_TOG used to set, clear and toggle selected bits.
