Description
Reset. Input pin, active low. An internal pull-up is provided.
General-Purpose Input and General-Purpose Output P2.1/ I
pin may be the UART Data carrier Detect pin.
This is a multi function input/output pin.
General-Purpose Input and General Purpose Output P2.2/ Boot mode input select pin. When
this pin is held low during any reset sequence, the part will enter UART download mode.
This is a dual function input/output pin.
External Crystal Oscillator Output Pin. Optional 32.768kHz source for Real time clock.
External Crystal Oscillator Input Pin. Optional 32.768kHz source for Real time clock.
