Notes
:
1.
Port 0is configured inpush-pull output mode (output is high). Ports 2, 3,4 and5 are configured in bi-directional weakpull-up mode resistor.
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.
2.
The CPU is fed by a 24 MHz frequency issued by the Main Clock Controller. VSYNC is tied to
V
SS
, HSYNCis driven bya 15625Hz clock.
All peripherals working including Display.
