Data Transfer Operation
Figure 13-13 shows timing when internal termination is used.
Figure 13-13. Line Read Burst (2-1-1-1), Internal Termination
Figure 13-14 shows a line access read with one wait state programmed in CSCRn 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 13-14. Line Read Burst (3-2-2-2), External Termination
Figure 13-15 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.
