FUNCTIONAL DESCRIPTION CPU 8-bit 6502 compatible CPU operates at 6MHz. Address bus is 16-bit and data bus is 8-bit. The non-maskable interrupt (/NMI) of 6502 is modified to be maskable and is defined as INT0 with higher priority. The interrupt request (/IRQ) of 6502 is defined as INT1 with lower priority. Please refer the 6502 reference menu for more detail. RAM The 1024 bytes SRAM include : 128 bytes SRAM are from $0080H to $00FFH 256 bytes SRAM are from $0100H to $01FFH 256 bytes SRAM are from $0200H to $02FFH 256 bytes SRAM are from $0300H to $03FFH 128 bytes SRAM are from $0400H to $047FH The 32 bytes SRAM bit addressible are from $0500H to $05FFH ROM For WT6148, ROM address is located from $4000h to $FFFFh. For WT6160, ROM address is located from $1000h to $FFFFh. The following addresses are reserved for special purpose : $FFFAh (low byte) and $FFFBh (high byte) : INT0 interrupt vector. $FFFCh (low byte) and $FFFDh (high byte) : program reset interrupt vector. $FFFEh (low byte) and $FFFFh (high byte) : INT1 interrupt vector.
