IMX6 MMDC fast or slow precharge PD?

The spreadsheet/script in https://community.freescale.com/docs/DOC-94917 sets MDPDC bit7 SLOW_PD=0 indicating fast precharge PD mode, yet the MR0 value written to the DRAM sets bit12=0 indicating slow precharge PD. The TRM states in the description of MDPDC SLOW_PD that it should be set the same as memory (which makes sense). Therefore I believe the spreadsheet/script to be in error.


Does Freescale have any recommendations on if the values should be set to fast precharge PD or slow?
