9.4.
Please take the following points into account when referring to the timing diagrams.
The clock frequency of the SYSCLK signal can be set to one of the following divisions of the internal bus clock (GBUSCLK):
1/3, 1/4, 1/5, or 1/6. Also, the operating reference clock frequency can be set to one of the following divisions of the internal
bus clock (GBUSCLK) for each channel: 1/3, 1/4, 1/5, or 1/6. (See 9.2.9.) The timing diagrams indicate the SYSCLK signal
clock frequency and channel operating reference clock frequency as being equivalent.
Both the BWE* signal and BE* signal are indicated in all timing diagrams. The setting of the Channel Control Register
(EBCCRn) determines whether the BWE* pin will function as BWE* or BE*.
All Burst cycles in the timing diagrams illustrate examples in which the address increases by increments of 1 starting from
0. However, cases where the CWF (Critical Word First) function of the TX49 core was used or the decrement burst function
performed by the DMA Controller was used are exceptions.
The timing diagrams display each clock cycle currently being accessed using the symbols described in the following table.
