Memory Organization

The XC886/888 CPU operates in the following five address spaces:

• 12 Kbytes of Boot ROM program memory

• 256 bytes of internal RAM data memory

• 1.5 Kbytes of XRAM memory

(XRAM can be read/written as program memory or external data memory)

• a 128-byte Special Function Register area

• 24/32 Kbytes of Flash program memory (Flash devices); or

24/32 Kbytes of ROM program memory, with additional 4 Kbytes of Flash

(ROM devices)

Figure 7 illustrates the memory address spaces of the 32-Kbyte Flash devices. For the

24-Kbyte Flash devices, the shaded banks are not available.
