1.4
The F-ZTAT Version Onboard Programming
There are 2 modes on the F-ZTAT version: a mode that writes and overwrites programs using the
special writer and a mode that writes and overwrites programs onboard the application system.
When rebooting after setting each mode pin and FWP pin during the reset condition, the
microcomputer will transfer to one of the modes indicated in figure 1.6. In the user mode, data can
be read from the flash memory but cannot be written or deleted. Use the boot mode and the user
program mode to write to the flash memory or delete data.
In the boot mode, SCI1 (TXD1, RXD1) is used for data transfer. It is possible to automatically
adjust the transfer bit rate to the transfer bit rate of the host.
