29.3 Example of Minimum Connection to Flash Microcomputer
Programmer
The connection between MOD and the flash microcomputer programmer is not required
if the pins are set as shown in Figure 29.3-1 during serial writing (serial write mode:
MOD="H", P12="H", P13="L").

Example of Minimum Connection to Flash Microcomputer Programmer

Figure 29.3-1 shows an example of the minimum possible connection to the flash microcomputer
programmer.
The TTXD pin on the flash microcomputer programmer is connected to P10/UI0 and outputs low until data
transfer starts. Setting P10/UI0=Low in this way specifies that serial write mode uses clock synchronous
communications.
Note that a user power supply is required for serial writing.
