DESCRIPTION
P Power supply input pins. Place the 0.1µF bypass capacitor between the VDD and VSS pin.
RST: System reset input pin. Schmitt trigger structure, low active, normal stay to
I, P “high”.
VPP: OTP programming pin.
I External oscillator input pin. RC mode input pin.
I/O External oscillator output pin. In RC mode is P1.4 I/O without pull-up resistor
I Port 0.0 and shared with INT0 trigger pin (Schmitt trigger) / Built-in pull-up resistors.
I/O Port 1.0~Port 1.4 bi-direction pins / Built-in pull-up resistors.
I/O Port 2.0~Port 2.7 bi-direction pins / Built-in pull-up resistors.
