Example of Serial Programming Connection

Inputting MOD="H" from TAUX3 on the AF220, AF210, AF120, or AF110 to the mode pin,
which is set to MOD="L" by the user system, sets the mode to serial write mode (serial
write mode: MOD="H", P12="H", P13="L").
Example of Serial Programming Connection
Figure 29.2-1 shows an example connection for serial writing.
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.
