TV-Out Extension
Software Controlled LEDs
The Chrontel
by converting LCD signals to TV signals.
The CH7024 is a TV encoder device which encodes the video signals and generates synchronization
signals for NTSC and PAL standards. Supported TV output formats are NTSC-M, NTSC-J, NTSC-433,
PAL-B/D/G/A/I, PAL-M, PAL-N and PAL-60. The CH7024 provides video output support for CVBS or S-
video.
Figure 4-12. TV-Out Extension Port
Three users LED are provided for general use. The LEDs are connected to PIO port lines, allowing their
control through either GPIO or PWM control.
PE[0..30]
LEDs D6 to D8 are software controlled by PIO pins.
LEDs D9 to D11 indicate Ethernet traffic and link status. These are automatically managed by on-chip
microcontroller hardware. See
