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

unless otherwise specified)
Note: The value left hand two columns show the formula used to calculate the timing minimum or maximum from the oscillator clock period,
prescale value and number of wait cycles inserted.
The value right hand two columns show the timing minimum for an external clock at 24 MHz divided by 2, prescale value of zero and zero
wait status.

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.
