P0.0–P0.7
General I/O port (8-bit), configurable for
digital input or push-pull output.
General I/O port (2-bit), configurable for
digital input or n-channel open-drain output.
P1.0–P1.1 can withstand up to 6-volt loads.
Multiplexed for alternative use as external
interrupt inputs INT0–INT1.
General I/O port (4-bit), configurable for
digital input or n-channel open-drain output.
P1.0–P1.1 can withstand up to 6-volt loads.
High current port (10mA).
General I/O port (4-bit), configurable for
digital input or push-pull output.
General I/O port (6-bit). I/O mode or n-
channel open-drain, push-pull output mode
is software configurable. Pins can withstand
up to 5-volt loads.
P2.2: OTP SCLK, P2.3: OTP SDA
General I/O port (2-bit). I/O mode or n-
channel open-drain, push-pull output mode
is software configurable. Pins can withstand
up to 5-volt loads.
Each pin has an alternative function.
P2.5: PWM0 (14-bit PWM output)
P2.7: OSDHT (Halftone signal output)
General I/O port (2 bits), configurable for
digital input or n-channel open-drain output.
Multiplexed for alternative use as external
interrupt inputs ADC0–ADC1.
Output pin for 14-bit PWM0 circuit
Analog inputs for 4-bit A/D converter
