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?
