Sega 315-5338A
I/O Controller
Custom 100-pin QFP LSI. Supports 7 8-bit input/output ports and can
directly interact with dual port RAM. Also supports a master/slave
configuration where one controller acts as master and sends commands
and data over a serial link to another controller.
TODO:
- Serial
- Slave mode
- and probably lots more
