40 / 56 page  Rev. PrB | Page 40 of 56 | November 2008 ADSP-21469/ADSP-21469W Preliminary Technical Data Parallel Data Acquisition Port (PDAP) The timing requirements for the PDAP are provided in Table 37. PDAP is the parallel mode operation of Channel 0 of the IDP. For details on the operation of the PDAP, see the PDAP chapter of the ADSP-2146x SHARC Processor Hardware Reference. Note that the most significant 16 bits of external PDAP data can be provided through the DATA7-0 pins. The remaining four bits can only be sourced through DAI_P4–1. The timing below is valid at the DATA7–0 pins. Table 37.

Source pins for SCLK and FS are: 1) DAI pins, 2) CLKIN through PCG, or 3) DAI pins through PCG. Figure 27.
