3.2 Program Memory Block Switching
The program memory block switching feature of the device
allows either Block 1 or the lowest 8 KByte of Block 0 to be
used for the lowest 8 KByte of the program address space.
SFCF[1:0] controls program memory block switching.

Program Memory Block Switching
Block 1 is not visible to the PC;
Block 1 is reachable only via In-Application Programming from 000H - 1FFFH.
Block 1 is overlaid onto the low 8K of the program address space; occupying address locations 0000H - 1FFFH.
When the PC falls within 0000H - 1FFFH, the instruction will be fetched from Block 1 instead of Block 0.
Outside of 0000H - 1FFFH, Block 0 is used. Locations 0000H - 1FFFH of Block 0 are reachable through
In-Application Programming.
