Interrupt Request 1
One of eight external lines that can request a service routine, via the internal interrupt controller,
from the SC140 core.
Data Parity 1
The agent that drives the data bus also drives the data parity signals. The value driven on the data
parity one pin should give odd parity (odd number of ones) on the group of signals that includes data
parity 1 and D[8–15].
External Bus Grant 2
The MSC8101 asserts this pin to grant bus ownership to an external bus master.
Interrupt Request 2
One of eight external lines that can request a service routine, via the internal interrupt controller,
from the SC140 core.
Data Parity 2
The agent that drives the data bus also drives the data parity signals. The value driven on the data
parity two pin should give odd parity (odd number of ones) on the group of signals that includes data
parity 2 and D[16–23].
External Data Bus Grant 2
The MSC8101 asserts this pin to grant data bus ownership to an external bus master.
Interrupt Request 3
One of eight external lines that can request a service routine, via the internal interrupt controller,
from the SC140 core.
Data Parity 3
The agent that drives the data bus also drives the data parity signals. The value driven on the data
parity three pin should give odd parity (odd number of ones) on the group of signals that includes
data parity 3 and D[24–31].
External Bus Request 3
An external master asserts this pin to request bus ownership from the internal arbiter.
Interrupt Request 4
One of eight external lines that can request a service routine, via the internal interrupt controller,
from the SC140 core.
Data Parity 4
The agent that drives the data bus also drives the data parity signals. The value driven on the data
parity four pin should give odd parity (odd number of ones) on the group of signals that includes data
parity 4 and D[32–39].
DMA Request 3
An external peripheral uses this pin to request DMA service.
External Bus Grant 3
The MSC8101 asserts this pin to grant bus ownership to an external bus master.
