803 / 1348 page  Chapter 21 External Bus Interface (S12XEBIV2) MC9S12XDP512 Data Sheet, Rev. 2.21 Freescale Semiconductor 805 21.5.2.2 Example 2b: Emulation Expanded Mode 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 R/W signals. Figure 21-6 shows the PRU connection with the available external bus signals in an emulator application. Figure 21-6. Application in Emulation Expanded Mode The timings of accesses with 1 stretch cycle are shown in • Figure ‘Example 2b: Emulation Expanded Mode — Read with 1 Stretch Cycle’ • Figure ‘Example 2b: Emulation Expanded Mode — Write with 1 Stretch Cycle’ The associated timing numbers are given in • Table ‘Example 2b: Emulation Expanded Mode Timing VDD5 = 5.0 V (EWAITE = 0)’ (this also includes examples for alternative settings of 2 and 3 additional stretch cycles) Timing considerations: • If no stretch cycle is added, the timing is the same as in Emulation Single-Chip Mode.
