Parallel Data Acquisition Port (PDAP)
The timing requirements for the PDAP are provided in
Table 29
. PDAP is the parallel mode operation of channel 0 of
the IDP. For details on the operation of the IDP, see the IDP
chapter of the
ADSP-2136x SHARC Processor Hardware Refer-
ence
. Note that the most significant 16 bits of external PDAP
data can be provided through either the parallel port AD15–0 or
the DAI_P20–5 pins. The remaining 4 bits can only be sourced
through DAI_P4–1. The timing below is valid at the
DAI_P20–1 pins or at the AD15–0 pins.
