TURBO <- |01 16| -> TURBO/2
/B -> |02 15| -> TURBO/4
/START -> |03 14| <- /A
/SELECT -> |04 13| -- VCC
/DOWN -> |05 12| -- GND
/RIGHT -> |06 11| <- STROBE
/UP -> |07 10| <- CLK
/LEFT -> |08 09| -> D0
'-------'
Notes:
- TURBO, TURBO/2, TURBO/4 can be used as turbo input for button A/B (on the tested pad, TURBO was used and other pins were NC),
- They toggle on the every / every second / every fourth rising edge of the (CLK and not STROBE) signal respectively and there is around 82ns delay between the transition
- After 8 edges of CLK signal, D0 goes low (on most pads, it goes high)
