Notes:
1. Port 0 is configured in push-pull output mode (output is high). Ports 2, 3, 4 and 5 are configured in bi-directional weak pull-up mode resistor.
2. The CPU is fed by a 24 MHz frequency issued by the Main Clock Controller. VSYNC is tied to
3. The CPU is fed by a 24 MHz frequency issued by the Main Clock Controller. VSYNC is tied to
4. VSYNC and HSYNC tied to

The external CLOCK pin (OSCIN) is driven by a square wave external clock at 8 MHz. The internal clock prescaler is in divide-by-1 mode.
All peripherals working including Display.
The TDSRAM interface and the Slicers are working; the Display controller is not working.
