The SCL0 and SDA0 pins are available in µPD784225Y Subseries only. 2. Connect the TEST pin to VSS0 directly or via a pull-down resistor. For the pull-down connection, use of a resistor with a resistance ranging from 470 Ω to 10 kΩ is recommended. Caution Connect the AVSS pin to VSS0. Remark When using in applications where noise from inside the microcomputer has to be reduced, it is recommended to take countermeasures against noise such as supplying power to VDD0 and VDD1 independently, and connecting VSS0 and VSS1 to different ground lines. |
