4.1.2 Circuit connection examples
The circuit design on the target system varies depending on the used connector and interface signals.
The following (1) to (3) are the major purpose of use. Confirm the purpose, refer to Table 4-5 and see the
relevant circuit connection example for specifications.
Caution The constants described in the circuit connection example are reference values. If you perform
flash programming aiming at mass production, thoroughly evaluate whether the specifications of
the target device are satisfied.
(1) Used to perform on-chip debugging and flash programming via one 16-pin connector.
(2) Used to perform on-chip debugging via a 10-pin connector.
* This type of circuit connection can be used with on-chip debugging emulator QB-78K0MINI.
(3) Used to perform flash programming.
