14. EXPANSION FUNCTION
14.2 Expansion memory
Expansion function memory is divided by 3 patterns ; Slice RAM, CRC registers and expansion registers
(Humming decoder operates by the register placed on SFR). Data writing and read out to the Slice RAM, CRC
registers and the expansion registers are carried out per 16 bit unit by the data setting register (addresses 020E16,
021016, 021216, 021416, 021616 and 021816) placed on SFR.
Contents of each memory and data setting register are shown in Table 14.1.
