FUNCTION DESCRIPTIONS 5.1 Oscillator SNC658 accepts crystal oscillator / ceramic resonator or RC type oscillator (selected by pin CKSEL) for system clock. The typical circuit diagrams for oscillator are listed as follows. VD D S NC 6 5 8 15 p F S NC 6 5 8 8MH Z C KS E L XO U T /R O S C XIN CKS E L XO U T /R O S C XIN 10 0 K 8MHZ Crystal 15 p F 8M Rosc 5.2 ROM SNC658 contains 64K words (12-bit) internal ROM. Program, voices, melodies, data, and instrument waveforms share the same ROM with the others. 5.3 RAM SNC658 contains 256 nibble RAM. The 256 nibble RAM is separated into four pages (page 0, page1, page2 and page 3). An implicit page indicator is utilized to specify page address. Four instructions, PAGE0, PAGE1, PAGE2 and PAGE3, can switch the page indicator. All 64 nibbles of each page can be accessed by direct mode (to specify M0 ~ M63 in the data transfer type instructions.) 5.4 Power Down Mode “End” instruction will let SNC658 enter power down mode and consumer very little amount of current.
