read RAM
write RAM
RAM refresh(needed at using DRAM or Pseudo SRAM)
output RAM data to upper 16 bits of DBUS
output RAM data to lower 8 bits of DBUS
output upper 16 bits of DBUS data to data register for writing
output lower 8 bits of DBUS data to data register for writing
(at external RAM-4bit, output the middle 8 bits to data register for writing)
use upper 16bits of DBUS data for address
upper 8bits of DBUS data to pointer
@DADR
@OFP
Peak Detection
Peak detection finds upper 16 bits of DBUS data as binary. The relation of input data and transformed value which
shows the size of data is as follows. If this value is used as indirect shift of @SHR command, data can be
normalized.
