3    Sega 315-5296 I/O chip
4   
5    Sega 100-pin QFP, with 8 bidirectional I/O ports, and 3 output pins.
6    It also has chip select(/FMCS) and clock(CKOT) for a peripheral device.
7    Commonly used from the late 80s up until Sega Model 2.
8
9    The I/O chip has 64 addresses:
10    $00-0F : I/O ports, security, configuration registers
11    $10-1F : Unused (no effect when read or written)
12    $20-3F : Unused (enables /FMCS output, eg. to YM2151 /CS)
13
14    On System 16 derivatives, the unused locations return the 68000 prefetch
15    value off the bus when read.

11    $10-1F : Unused (no effect when read or written)
12    $20-3F : Unused (enables /FMCS output, eg. to YM2151 /CS)
