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 is the output for the
6-bit PWM7. P3.5 to P3.7 have no alternative
functions and are only available with the LQFP100
package.
core ground
Port 0. 8-bit programmable bidirectional port.
P0.5 and P0.6 have 8 mA current sinking capability for
direct drive of LEDs.
analog ground
Composite Video Baseband Signal (CVBS) input. A
positive-going 1 V (peak-to-peak) input is required.
Connected via a 100 nF capacitor.
CVBS sync filter input. This pin should be connected
to V
Reference current input for analog circuits, connected
to V
De-interlace output synchronised with the VSYNC
pulse to produce a non-interlaced display by
adjustment of the vertical deflection circuits.
