Memory Organization
The SAL-XC886 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
Figure 6 illustrates the memory address spaces of the 32-Kbyte Flash devices. For the
24-Kbyte Flash devices, the shaded banks are not available.
