3.3 Target Reset Processing
The target reset processing differs depending on whether or not this product is connected to the target device.
Both types of processing are described below.
(1) When using jumper
(a) With QB-78K0MINI
Connect using the connection cable for QB-78K0MINI.
(b) With this chip
Short pins 1 and 2 (target connector for QB-78K0MINI) as is shown in Figure 3-2.
