3. RAM: 512 X
8 bits
The built-in 512 X 8-bit SRAM is used for data memory and stack area. The RAM addressing range is from $0080 to $027F.
The contents of RAM are undetermined at power-up and are not affected by system reset. Software programmers can
allocate stack area in the RAM by setting stack pointer register (S). Since the 6502 default stack pointer is $01FF,
programmers must set S register to FFH when starting the program.

4.1. BootROM: 2K X 8 bits
NT68F62 Provides 2K bytes of Boot-ROM for ISP. The memory space is from $7800 to $7FFF. The addresses, from $7FFA
to $7FFF, are reserved for the 6502 CPU vector.
4.2. Flash memory: 32K X
8
bits
NT68F62 provides 32K flash memory space for programming. The flash memory space is located from $8000 to $FFFF.
The addresses, from $FFFA to $FFFF, are reserved for the 6502 CPU vectors, thus users must arrange them by
themselves. This flash memory can be progammed repeatly at limited times to guarantee its performance.
