In addition Delay RAM is properly used by MAL [2:0] as RAM of 024, 2048, and 4096 word, as
shown in the following figure.

The same or overlapping block cannot be accessed by different decimation ratio.
Moreover, decimation ratio set up here and decimation ratio set up by DECI command need to be
fundamentally made in agreement.
DECI bit set up with an offset address determines decimation ratio of memory access, and a setup
to DECI command determines the band of a decimation filter.
Note 14: Since C block is assigned to Keycontrol R-ch, and D block is assingned to Keycontrol L-ch, it is neseccary
to be set to KEY
= 0H when using it here.
