Notes 1. Intermediate-level input is enabled when the MPOWER pin is set for low-level output.
2. When the bus hold function is used : Pull up.
When the bus hold function is not used : Connect to VDD.
3. When FIR unit is used : Attach an oscillator.
When FIR unit is not used : Connect to VDD.
4. This pin can be switched by software between function-pin and output-port uses.
