extended program memory
The ’5409 CPU uses a paged extended memory scheme in program space to allow access of up to 8M program
memory locations. In order to implement this scheme, the ’5409 includes several features that are also present
on the ’548/’549 devices:
Twenty-three address lines, instead of sixteen
An extra memory-mapped register, the XPC register defines the page selection. This register is
memory-mapped into data space to address 001Eh. At a hardware reset, the XPC is initialized to 0.
Six extra instructions for addressing extended program space. These six instructions affect the XPC.
–
FB[D]pmad (23 bits) – Far branch
–
FBACC[D] Accu[22:0] – Far branch to the location specified by the value in accumulator A or
accumulator B
–
FCALL[D]pmad (23 bits) – Far call
–
FCALA[D] Accu[22:0] – Far call to the location specified by the value in accumulator A or accumulator B
–
FRET[D]– Far return
–
FRETE[D]– Far return with interrupts enabled
In addition to these new instructions, two ’54x instructions are extended to use 23 bits in the ’5409:
–
READA data_memory (using 23-bit accumulator address)
–
WRITA data_memory (using 23-bit accumulator address)
All other instructions, software interrupts, and hardware interrupts do not modify the XPC register and access
only memory within the current page.
Program memory in the ’5409 is organized into 127 pages that are each 64K in length, as shown in Figure 2.

Refer to Figure 1. 5409 Memory Map.
The Lower 32K words of pages 1 through 126 are available only when the OVLY bit is cleared to 0. If the OVLY bit is set to 1,
the on-chip RAM is mapped to the lower 32K words of all program space pages.
