TEA
The write cycle starts in C1. During C1, the MCF5272 places valid values on the address bus
(A[22:0]) and the chip select signal.
During C2, the MCF5272 drives the data bus, the byte strobes, and R/W.
During C3, the selected device detects an error and asserts TEA. At the end of C3 or Cx, the
MCF5272 samples the level of TEA. If it is asserted, the transfer of the longword is aborted and
the transfer terminates.
Figure 20-20. Longword Write Access To 32-Bit Port Terminated with TEA Timing
(H)
shows a longword write access to a 32-bit port with a transfer error.
This example shows TEA being asserted during C3. TEA can be asserted
earlier or later than C3.
If TA is asserted when debug transfer error-acknowledge (TEA) is asserted,
the transfer is terminated with a bus error.
