2.15.2 Expansion memory
Expansion function memory is divided by 2 patterns ; Slice RAM and expansion register. (Humming
decoder operates by the register placed on SFR). Data writing and read out to the Slice RAM and the
expansion register are carried out 16 bit unit by the data setting register (addresses 020E16, 021016,
021616 and 021816) placed on SFR.
Contents of each memory and data setting register are shown in Table 2.15.1.
