All members of the High–Speed Microcontroller Family
are designed to directly address up to 64KB of program
and data memory. Occasionally, however, an application
will require more memory than is either available
on–chip or through the use of the 64KB memory map.
The High–Speed Microcontroller Family includes many
features which make it easy to address program and/or
data memory greater than 64KB. Bit–addressable I/O
ports allow single instruction modification of control
lines, which can be used to bank switch or page
between multiple memory devices. The ROMSIZE feature
allows easy memory resizing for devices with on–
chip memory.
