See Host Port Usage Considerations in the DSP56362 User Design Manual.
In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable.
V
The read data strobe is HRD in the dual data strobe mode and HDS in the single data strobe mode.
The “last data register” is the register at address $7, which is the last location to be read or written in data transfers. This is
RXL/TXL in the little endian mode (HBE = 0), or RXH/TXH in the big endian mode (HBE = 1).
This timing is applicable only if a read from the “last data register” is followed by a read from the RXL, RXM, or RXH registers
without first polling RXDF or HREQ bits, or waiting for the assertion of the HOREQ signal.
This timing is applicable only if two consecutive reads from one of these registers are executed.
