TMS320C6655: DDR3_CONFIG_23

Part Number: TMS320C6655

Tool/software:

Hi,

Because DDR3_CONFIG_23 is "NA for TCI6612/13/14 and C665x devices" in SPRUGV8E, customer checked the registers(25~28, 34~37, 43~46, 52~55)

however, at page13 of SPRUGV8E, there is below description.

"The Expanded Fixed Ratio Register DSPs can have unique fixed ratio values programmed for each byte lane. This solution is currently not being supported because it is not compatible with automatic leveling."

1. Does this mean that the registers(25~28, 34~37, 43~46, 52~55) is not available?

2. in 499line of evmc6657.c and example 20 in page 14, DDR3_CONFIG_23 is not used. Is this register not available?

Thanks.
