Even if the P83, P84, SIN1, SOT1, and SCK1 pins are used for the user system, the control circuit shown in
Figure 25.1-2 is required. (The /TICS signal of the flash microcontroller programmer can be used to
disconnect the user circuit during serial programming.)

"25.2 Example of Serial Programming Connection (User Power Supply Used)" to "25.5 Example of
Minimum Connection to Flash Microcontroller Programmer (Power Supplied from Programmer)" present
examples the following 4 types of serial programming connection. See each Section as required.
• Example of serial programming connection (user power supply used)
• Example of serial programming connection (power supplied from the programmer)
• Example of minimum connection to the flash microcontroller programmer (user power supply used)
• Example of minimum connection to the flash microcontroller programmer (power supplied from the
Controls programming mode from the flash microcontroller programmer.
In programming mode, the CPU internal operation clock signal is one multiple of the
PLL clock signal frequency. Therefore, because the oscillation clock frequency
becomes the internal operation clock signal, the oscillator used for serial reprogram-
ming is 4 MHz to 16 MHz.
Input "L" level to P83 and "H" level to P84.
Use UART1 as CLK synchronous mode.
This pin is used to stabilize the power supply.
Connect to a external ceramic capacitor of approximately 0.1 µF or more.
If the programming voltage (5 V ± 10%) is supplied from the user system, the flash
microcontroller programmer need not be connected. Connect so that the power supply
of the user side is not short-circuited.
Common to the ground of the flash microcontroller programmer.
