Function
RAM Address Bus
This bus provides the address of the current
bus cycle. RMADR15 is the MSB.
RAM Data Bus
This bidirectional three-state bus provides
the data path between the IWE8 and the
external memory. RMDAT32 is parity bit,
RMDAT31 is the MSB.
RAM Chip Select
This signal enables read or write accesses
to the external memory
RAM Output Enable
This signal enables the outputs of the
external memory
RAM Write Enable
This output is asserted when a write access
to the external memory
