If the P00, SIN, SOT, and SCK pins are used also by the user system, the following control
circuit is required.
microcontroller programmer during serial programming.
Sections 24.2 to 24.5 show the following examples of serial programming connections for
reference:
• Example of serial programming connection (when user power supply is used)
• Example of serial programming connection (when power is supplied from a writer)
• Example of minimal connection with the flash microcontroller programmer (when user power
supply is used)
• Example of minimal connection with the flash microcontroller programmer (when power is
supplied from a writer)
