886 / 1348 page  Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2) MC9S12XDP512 Data Sheet, Rev. 2.21 888 Freescale Semiconductor A valid edge on an input is detected if 4 consecutive samples of a passive level are followed by 4 consecutive samples of an active level directly or indirectly. The filters are continuously clocked by the bus clock in run and wait mode. In stop mode, the clock is generated by an RC-oscillator in the port integration module. To maximize current saving the RC oscillator runs only if the following condition is true on any pin individually: Sample count <= 4 and interrupt enabled (PIE = 1) and interrupt flag not set (PIF = 0). 22.4.4 Expanded Bus Pin Functions All peripheral ports T, S, M, P, H, J, AD0, and AD1 start up as general purpose inputs after reset. Depending on the external mode pin condition, the external bus interface related ports A, B, C, D, E, and K start up as general purpose inputs on reset or are configured for their alternate functions. Table 22-70 lists the pin functions in relationship with the different operating modes. If two entries per pin are displayed, a ‘mux’ indicates time-multiplexing between the two functions and an ‘or’ means that a configuration bit exists which can be altered after reset to select the respective function (displayed in italics). Refer to S12X_EBI section for details. Table 22-70.
