6 / 30 page 6 MLC0xxB Series Technical Summary MEGAWIN Memory Map There are 256 bytes SRAM in MLC0xxB series. They are working RAM (0000H to 007FH) and stacks (0180H to 01FFH). The address 0100H to 17FH are shared with address 0000H to 007FH. The address 00C0H to 00FFH and 0200H to 027FH are special function registers area. The bank select function, ranged from 4000H to 7FFFH, is used for extending memories if the ROM size is more than 32K bytes in MLC0xxB series. The default bank number is 00H after power on or reset. There are 1024K ~ 48K bytes program/data ROM in MLC0xxB series. It is combined with 32K program/data ROM and bank switching data ROM. The ROM address from 4000H to FFFFH can store program, voice data, melody notes and other data. The address mapping of MLC0xxB series is shown as below.
