When the MPC561/MPC563 initiates a burst access, the bus interface recognizes the RETRY assertion as
a retry termination only if it detects it before the first data beat was acknowledged by the slave device.
When the RETRY signal is asserted as a termination signal on any data beat of the access after the first
(being the first data beat acknowledged by a normal TA assertion), the MPC561/MPC563 recognizes
RETRY as a transfer error acknowledge.
