manipulation such as writing and erasing via a dedicated single-line UART. To write the flash memory off-board, a
dedicated program adapter (FA series) is necessary.
23.3 Communication Mode
communication using the TOOL0 pin via a dedicated single-line UART of the 78K0R/KE3.
PG-FP4, FL-PR4, PG-FP5, FL-PR5, or MINICUBE2 for details.
23.2 Programming Environment
The environment required for writing a program to the flash memory of the 78K0R/KE3 is illustrated below.
A host machine that controls the dedicated flash memory programmer is necessary.
To interface between the dedicated flash memory programmer and the 78K0R/KE3, the TOOL0 pin is used for
Communication between the dedicated flash memory programmer and the 78K0R/KE3 is established by serial
Notes 1.
The dedicated flash memory programmer generates the following signals for the 78K0R/KE3. See the manual of
Transfer rate: 115,200 bps to 1,000,000 bps
2.
Host machine
This pin is not required to be connected when using PG-FP5 or FL-PR5.
Connect SI/RxD or SO/TxD when using QB-MINI2.
