Description
CR oscillator output pin
When the internal CR oscillator is used, connect to OSC1, OSC3 through a resistor.
O OSC1 – OSC2: Using in normal display mode, partial display mode 0
OSC3 – OSC4: Using in partial display mode 1
When an external oscillator is used, OSC1 pin is connected to VDD or VSS.
External clock input pin
I When an external input is used, it is input to this pin. But the internal oscillator is used,
this pin is connected to VDD or VSS.
Internal voltage regulator output pin
O The regulator output port from this pin is used as a power supplier for an internal digital
block via VDD1 pins.
