■ PROGRAMMING AND ERASE FLASH MEMORY
1.
Flash Memory
The flash memory incorporates a flash memory interface circuit that allows read access and program access
from the CPU to be performed in the same way as mask ROM. Programming and erasing flash memory is also
performed via the flash memory interface circuit by executing instructions in the CPU. This enables the flash
memory to be updated in place under the control of the CPU, providing an efficient method of updating program
and data.
2.
Flash Memory Features
16 K byte
× 8-bit configuration or 8 K byte × 8-bit configuration*
Automatic programming algorithm (Embedded Algorithm)
Data polling and toggle bit for detection of program/erase completion
Detection of program/erase completion via CPU interrupt
Compatible with JEDEC-standard commands
No. of program / erase cycles : Minimum 10,000
* : Check section “Memory Space”.
3.
Procedure for Programming and Erasing Flash Memory
Programming and reading flash memory cannot be performed at the same time. Accordingly, to program or erase
flash memory, the program must first be copied from flash memory to RAM so that programming can be per-
formed without program access from flash memory. Also for flash memory program or erase, a high voltage
(instead of an external pullup) must be applied to external reset RST pin. Check section
