1.4.3 Circuit Design Guide
At the FLASH programming, the programming tool needs 4 signal lines that are DSCL, DSDA, VDD, and VSS. When
you design the PCB circuits, you should consider the usage of these signal lines for the on-board programming.
Please be careful to design the related circuit of these signal pins because rising/falling timing of DSCL and DSDA is
very important for proper programming.

NOTE)
1. In on-board programming mode, very high-speed signal will be provided to pin DSCL and DSDA.
And it will cause some damages to the application circuits connected to DSCL or DSDA port if the
application circuit is designed as high speed response such as relay control circuit. If possible, the
I/O configuration of DSDA, DSCL pins had better be set to input mode.
2. The value of R1 and R2 is recommended value. It varies with circuit of system.
