7.2 Introduction
The two Flash EEPROM modules (32-Kbyte and 28-Kbyte) for the
MC68HC912D60A serve as electrically erasable and programmable,
non-volatile ROM emulation memory. The modules can be used for
program code that must either execute at high speed or is frequently
executed, such as operating system kernels and standard subroutines,
or they can be used for static data which is read frequently. The Flash
EEPROM is ideal for program storage for single-chip applications
allowing for field reprogramming.
