NEO-ZMC part:
- SDA0,SDA1,SDA8~SDA15: Z80 address bus
- MA11~M21: M ROM address outputs
PRO-CT0 part, inputs:
- 12M: 12MHz clock, outputs next pixel on falling edge.
- C0~C31: C ROM data bus (2*16 bits). Gives all the pixel data needed for a 8 pixel line.
- H: When high, reverse bit order of pixels shifted out (used for sprites horizontal flipping)
- EVEN: Swap A/B pixels.
- LOAD: Latch C ROM data (on rising edge ?).
Outpus:
- DOTA: High when pixel A is opaque (color > 0)
- DOTB: High when pixel B is opaque (color > 0)
- GAD0~GAD3: Pixel A color data
- GBD0~GBD3: Pixel B color data
