Port 2: 8-bit programmable bidirectional port with alternative functions.
P2.0/TPWM is the output for the 14-bit high precision PWM; P2.1/PWM0 to
P2.7/PWM6 are the outputs for the 6-bit PWMs 0 to 6
Port 3: 8-bit programmable bidirectional port with alternative functions.
P3.0/ADC0 to P3.3/ADC3 are the inputs for the software ADC facility;
P3.4/PWM7/T2EX is the output for the 6-bit PWM7 or the Timer 2 control;
P3.5/INT5 is the external Interrupt 5; P3.6 and P3.7 have no alternative
functions
core ground
Port 0: 8-bit programmable bidirectional port (with alternative functions).
P0.0/RX and P0.1/TX are respectively the serial transmit and receive lines
for the UART; P0.2/INT2 to P0.4/INT4 are the external interrupts 2 to 4;
P0.5 and P0.6 have no alternative functions and have 8 mA current sinking
capability for direct drive of LEDs
analog ground
2 composite video inputs selectable via SFR; a positive-going 1 V
(peak-to-peak) input is required and connected via a 100 nF capacitor
CVBS sync filter input; this pin should be connected to V
capacitor
reference current input for analog circuits and connected to V
24 k resistor
de-interlace output synchronized with the VSYNC pulse to produce a
non-interlaced display by adjustment of the vertical deflection circuits
OTP programming voltage
open-drain, active LOW output which allows selective contrast reduction of
the TV picture to enhance a mixed mode display
3.3 V analog power supply
pixel rate output of the BLUE colour information
