Chapter 4 Memory
Table 4-5

shows the memory block to be accessed through paging window ($00C0–$00FF).
Start address of memory block selected
Physical location $0000-$000E is RAM. Physical location $000F is register
X. D[X] register is mapped to address $000E only. The physical RAM in
$000E can be accessing through D[X] register when X register is either $0E
or $CE with PAGESEL is $00.
When PAGESEL register is $00, paging window is mapped to the first page
($00-$3F). Paged location $00C0–$00CE is mapped to physical location
$0000-$000E, i.e., RAM. Paged location $00CF is mapped to register X.
Therefore, accessing address $CE returns the physical RAM content in
$000E, accessing address $000E returns D[X] register content.
