18.4 Writing with Flash Memory Programmer
memory of the 78K0S/KA1+.
268
The following two types of dedicated flash memory programmers can be used for writing data to the internal flash
• FlashPro4 (PG-FP4, FL-PR4)
• FlashPro5 (PG-FP5, FL-PR5)
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
The contents of the flash memory can be rewritten after the 78K0S/KA1+ 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 18-4 for mounting of the test pad).
Data can be written to the flash memory with a dedicated program adapter (FA series) before the 78K0S/KA1+
is mounted on the target system.
Remark
The FL-PR4, FL-PR5, and FA series are products of Naito Densei Machida Mfg. Co., Ltd.
