Figure 18-14 shows a line access read with one wait state programmed in CSCRx to give
the peripheral or memory more time to return read data. This figure follows the same
execution as a zero-wait state read burst with the exception of an added wait state.
Figure 18-15 shows a burst-inhibited line read access with fast termination. The external
device executes a basic read cycle while determining that a line is being transferred. The
external device uses fast termination for subsequent transfers.
