On-board programming
Off-board programming
Self programming
Remarks 1. The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
The following two types of dedicated flash memory programmers can be used for writing data to the internal flash
Data can be written to the flash memory on-board or off-board, by using a dedicated flash memory programmer.
(1) On-board programming
(2) Off-board programming

Rewrite Method
The contents of the flash memory can be rewritten after the 78K0S/KB1+ has been mounted on the target
system. The connectors that connect the dedicated flash memory programmer and the test pad must be
mounted on the target system. The test pad is required only when writing data with the crystal/ceramic
resonator mounted (refer to Figure 19-4 for mounting of the test pad).
Data can be written to the flash memory with a dedicated program adapter (FA series) before the 78K0S/KB1+
is mounted on the target system.
Remark
2.
Refer to the following sections for details on the flash memory writing control function.
The FL-PR5 and FA series are products of Naito Densei Machida Mfg. Co., Ltd.
19.7 On-Board and Off-Board Flash Memory Programming
19.8 Flash Memory Programming by Self Programming
Flash memory can be rewritten after the device is mounted on the
target system, by using a dedicated flash memory programmer.
Flash memory can be rewritten before the device is mounted on the
target system, by using a dedicated flash memory programmer and a
dedicated program adapter board (FA series).
Flash memory can be rewritten by executing a user program that has
been written to the flash memory in advance by means of on-board/off-
board programming.
