3.5.1Timing Registers

XINTF signal timing can be tuned to match specific external device requirements such as setup and hold times to strobe signals for contention avoidance and maximizing bus efficiency. The timing parameters can be configured individually for each zone. This allows the programmer to maximize the efficiency of the bus, based on the type of memory or peripheral that the user needs to access. All XINTF timing values are with respect to XTIMCLK, which is equal to or one-half of the SYSCLKOUT rate, as shown in Figure 6-27.

For detailed information on the XINTF timing and configuration register bit fields, see the TMS320x281x DSP External Interface (XINTF) Reference Guide (SPRU067).

3.5.2XREVISION Register

The XREVISION register contains a unique number to identify the particular version of XINTF used in the product. For the F2812, this register is configured as described in Table 3-9.
