Connect directly or via a resistor to VDD.
Connect to VSS.^{Note 3}
Connect directly to VDD.^{Note 4}
Connect directly to VSS.
Notes 1. Use recommended connection above in I/O port mode (see Figure 5-2 Format of Clock Operation
Mode Select Register (OSCCTL)) when these pins are not used.
2. μPD78F041x only.
3. FLMD0 is a pin used when writing data to flash memory. When rewriting flash memory data on-board
or performing on-chip debugging, connect this pin to VSS via a resistor (10 kΩ: recommended).
4. When using port 2 as a digital port or for segment output, set it to the same potential as that of VDD.
