The primary configuration is reserved.
Data Parity 0
The agent that drives the data bus also drives the data parity signals. The value driven
on the data parity zero pin should give odd parity (odd number of ones) on the group of
signals that includes data parity 0 and D[0–7].
External PowerPC Bus Request 2
An external master asserts this pin to request bus ownership from the internal arbiter.
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 PowerPC 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 PowerPC 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 PowerPC Bus Request 3
An external master asserts this pin to request bus ownership from the internal arbiter.
