FUNCTIONAL DESCRIPTION
CPU
8-bit 6502 compatible CPU with 16-bit address bus and 8-bit data bus operates at 6MHz. 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 256 bits bit-addressable SRAM are from $0500H to $05FFH
Flash Memory
60K bytes flash memory for program. 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.
