MEM to Host Gear Ratio Mux
MEMNDGRCFG0: MEM Next Data Gear Ratio Configuration 0
This register consists of 8 nibbles of mux select data for the proper selection of gearing
behavior in the MC. This is the first of two registers to control the behavior for the
DRAM to host (Northbound) data flow for the “data_next” signaling.
MEM to Host Gear Ratio Mux for
MEMNDGRCFG1: MEM Next Data Gear Ratio Configuration 1
This register consists of 8 nibbles of mux select data for the proper selection of gearing
behavior in the MC for the 1:1 and 4:5 modes. This is the second register for MEM to
Host gearing control for the “data_next” signaling.
