μ
PD754264
6. EEPROM
The
μ
PD754264 incorporates 32 words
×
8 bit EEPROM (Electrically Erasable PROM) as well as static RAM (128
words
×
4 bit) as a data memory.
The EEPROM incorporated into the
μ
PD754264 has the following features.
(1) Written data is retained if power is turned off.
(2) 8-bit data manipulation (auto-erase/auto-write) is available by memory manipulation instruction as well as for
static RAM. However available instructions are restricted.
(3) It can reduce loads of software because the auto-erase and/or auto-write operation is performed by hardware.
(4) Write operation control using the interrupt request
The interrupt request is generated under following conditions.
Terminates write operation
Write status flag
It is possible to check whether enables or disables write operation by bit manipulation instructions.
