Interrupt Request 4
One of fifteen external lines that can request a service routine, via the internal interrupt
controller, from the SC140.
System Bus Data Parity 4
The agent that drives the data bus also drives the data parity signals. The value driven on the
data parity 4 pin should give odd parity (odd number of ones) on the group of signals that
includes data parity 4 and D[32–39].
DMA Acknowledge 3
The DMA drives this output to acknowledge the DMA transaction on the bus.
External Data Bus Grant 3
2
The MSC8113 asserts this pin to grant data bus ownership to an external bus master.

System Bus Data Parity 5
The agent that drives the data bus also drives the data parity signals. The value driven on the
data parity 5 pin should give odd parity (odd number of ones) on the group of signals that
includes data parity 5 and D[40–47].
DMA Acknowledge 4
The DMA drives this output to acknowledge the DMA transaction on the bus.

The agent that drives the data bus also drives the data parity signals. The value driven on the
data parity 6 pin should give odd parity (odd number of ones) on the group of signals that
includes data parity 6 and D[48–55].

System Bus Data Parity 7
The agent that drives the data bus also drives the data parity signals. The value driven on the
data parity 7 pin should give odd parity (odd number of ones) on the group of signals that
includes data parity 7 and D[56–63].
DMA Request 4
Used by an external peripheral to request DMA service.
