8 / 23 page SyncMOS Technologies International, Inc. SM8958A 8-Bits Micro-controller With 32KB flash & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.1 SM8958A 08/2006 8 Internal RAM Control Register (RCON, $85) bit-7 bit-0 Unused Unused Unused Unused Unused Unused RAMS1 RAMS0 Read / Write: - - - - - - R/W R/W Reset value: * * * * * * 0 0 SM8958A has 768 byte on-chip RAM which can be accessed by external memory addressing method only. (By instruction MOVX). The address space of instruction MOVX @Rn is determined by bit 1 and bit 0 (RAMS1, RAMS0) of RCON. The default setting of RAMS1, RAMS0 bits is 00 (page0). RAMS1 RAMS0 MOVX @Ri i=0,1 mapping to expended RAM address 0 0 $0000 ~ $00FF 0 1 $0100 ~ $01FF 1 0 $0200 ~ $02FF The port 0, port2, port3.6 and port3.7 can be used as general purpose I/O pin while port0 is open-drain structure. System Control Register (SCONF, $BF) bit-7 bit-0 WDR Unused Unused Unused Unused Unused OME ALEI Read / Write: R/W - - - - - R/W R/W Reset value: 0 * * * * * 0 0 WDR : Watch Dog Timer Reset. When system reset by Watch Dog Timer overflow. WDR will be set to 1, The bit 7 (WDR) of SCONF is Watch Dog Timer Reset bit. It will be set to 1 when reset signal generated by WDT overflow. User should check WDR bit whenever un-predicted reset happened. OME : 768 bytes on-chip RAM enable bit. The bit 1 (OME) of SCONF can enable or disable the on-chip expanded 768 byte RAM. The default setting of OME bit is 0 (disable). ALEI : ALE output inhibit bit, to reduce EMI. Setting bit 0 (ALEI) of SCONF can inhibit the clock signal in Fosc/6Hz output to the ALE pin. |
