After reset, the port register values are as shown below. Figure 4-1. Port Register Configuration ( µPD6P8, 6P8A) Notes 1. ×: Refers to the value based on the KI and S2 pin state. 2. ×: Refers to the value based on decrease of power supply voltage (0 when VDD ≤ VID) Remark VID: RAM retention detection voltage Table 4-1.
