This mode is used for emulation systems in which the target application is operating in normal expanded
mode.
If the external bus is used with a PRU, the external device rebuilds the data select and data direction signals
UDS, LDS, RE, and WE from the ADDR0, LSTRB, and RW signals.

ECLKX2 rising edges have the same timing as ECLK edges.
The timing for accesses to PRU registers, which take 2 cycles to complete, is the same as the timing
for an external non-PRR access with 1 cycle of stretch as shown in example 2b.
Figure ‘Example 2b: Emulation Expanded Mode — Read with 1 Stretch Cycle’
Figure ‘Example 2b: Emulation Expanded Mode — Write with 1 Stretch Cycle’
shows the PRU connection with the available external bus signals in an emulator application.
