Table 23.22 Timing at which BRDY Interrupts are Generated
Note: This function is valid only in the reading direction of reading from the buffer memory. In the
(4)
(a)
Figure 23.15 shows a diagram of the timing up to the point where the FRDY and DTLN bits are
determined when the pipe specified by the FIFO port has been switched (the CURPIPE bit in
C/DnFIFOSEL has been changed).
If the CURPIPE bits have been changed, access to the FIFO port should be carried out after
waiting 450 ns and 8 clock cycles at a peripheral clock after writing to C/DnFIFOSEL.
The same timing applies with respect to the CFIFO port, when the ISEL bit is changed.
