This mode is used for emulation systems in which the target application is operating in normal single-chip
mode.

Signals muxed with address lines ADDRx, i.e., IVDx, IQSTATx and ACCx, have the same timing.
LSTRB has the same timing as R/W.
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.
shows the PRU connection with the available external bus signals in an emulator application.
