I
Write: This signal initiates a write operation.
The WR input is internally sampled only if CS is
active. In this case the MTSC loads an internal
register with data from the data bus at the rising
edge of WR. WR is active low.
I/O
Data Bus: The data bus is used for
I/O
communication between the MTSC and a
I/O
processor.
