TrueFFS utilizes an 8KB memory window in the CPU address space consisting of four 2KB
sections, as depicted in Figure 11. When in Reset mode, the Programmable Boot Block in sections 0
and 3 will show the IPL (1KB), aliased twice, to support systems that search for a checksum at the
boot stage from the top and bottom of memory. Read cycles from sections 1 and 2 always return the
value 00H to create a fixed and known checksum. When in Normal mode, sections 1 and 2 are used
for the internal registers.
The addresses described here are relative to the absolute starting address of the 8KB memory
window.
