When MMAP = 0, on-chip program memory RAM occupies
2K words beginning at address 0x0000. Off-chip program
memory uses the remaining 14K words beginning at address
0x0800. In this configuration–when MMAP = 0–the boot
loading sequence (described below in “Boot Memory Inter-
face”) is automatically initiated when RESET is released.
When MMAP = 1, 14K words of off-chip program memory
begin at address 0x0000 and on-chip program memory RAM is
located in the upper 2K words, beginning at address 0x3800. In
this configuration, program memory is not booted although it
can be written to and read under program control.

When MMAP = 0, on-chip program memory RAM occupies
1K words beginning at address 0x0000. Off-chip program
memory uses the remaining 14K words beginning at address
0x0800. In this configuration–when MMAP = 0–the boot
loading sequence (described below in “Boot Memory Inter-
face”) is automatically initiated when RESET is released.
When MMAP = 1, 14K words of off-chip program memory
begin at address 0x0000 and on-chip program memory RAM is
located in the 1K words between addresses 0x3800–0x3BFF. In
this configuration, program memory is not booted although it
can be written to and read under program control.
