GAME PORT REGISTERS

The following abbreviations are used to indicate the Register Type:

R/W = Read/Write

R = Read from a speciﬁc address returns the value of a speciﬁc register. Write to the same address is to a different

W=Write

RO = Read Only

R/W1C = Read/Write 1 to Clear. Writing 1 to a bit clears it to 0. Writing 0 has no effect.
