12.6.2.2
This section contains more detail on the sequence of events for a system bus read with the controller as
master:
When the SEC performs a transaction as master, it is possible for the intended slave to terminate the transfer
due to an error. The SEC’s transaction requests are posted to the MPC8533E target queue, after which the
MPC8533E takes responsibility for completing the transaction or signaling error. An error in an SEC
initiated transaction is also reported by the SEC via the channel interrupt status register. The host will be
able to determine which channel generated the interrupt by checking the ISR for the channel ERROR bit.
12.6.2.3
This section contains more detail on the sequence of events for an system bus write with the controller as
master:
While the controller is satisfying a requests from one channel, it can still acknowledge and queue requests
from the other channels.
12.6.2.4
The controller also acts as a bus slave. As a slave, the controller simply responds to read and write
commands from the bus. When a write command is received from the bus, the controller takes the data

1. Channel asserts its bus read request to the controller.
2. Channel furnishes external read address, internal write address, and transfer length.
3. Controller sends request acknowledge to channel.
4. Controller asserts request to the system bus.
5. Controller waits for system bus read to begin.
6. When bus read begins, controller receives data from the master interface and performs a write to
