Hi,

 

I'm trying to configure the MMDC registers for its initialization as described in page 1700 of the IMX6SLLRM. I'm using the W63CH2MBV LPDDR3 chip from Winbond (see attached data sheet).

 

I have a question concerning the MMDC_MDCTL register, and more especially about the COL [22:20] part.

The Winbond data sheet describes (page 8), that the column address is 10 bits long for the x32 version, but the "least-significant column address C0 is not transmitted on the CA bus, and is implied to be zero".

Should I set the MMDC_MDCTL register for a 9 or 10 bits column?

 

Best,

Vincent
