SyncMOS Technologies Inc. SM8958A
Data Bank Control Register (DBANK, $86)
Data bank select enable bit BSE = 1 enables the data bank select function
Data bank select enable bit BSE = 0 disables the data bank select function
BS[3:0] setting will map $040~$07F RAM space to entire 1K byte on-chip RAM space.
Internal RAM Control Register (RCON, $85)
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).
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)
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.
