  • Page 9: Introduction

    The ERTEC 200 is intended for the implementation of PROFINET devices with RT and IRT functionality. With its integrated ARM946 processor and 2-port Ethernet switch with integrated PHYs and the option to connect an external host processor system to a local bus interface, it meets all the requirements for implementing PROFINET devices with integrated switch functionality.

    In this case, the ARM master would have to pause in a “Wait” until the IRT master enables the EMIF slave again. To prevent this situation, monitoring is integrated into the IRT switch, which enables the slave momentarily via an IDLE state after 8 consecutive data transfers (burst or single access).

    Access by the host is asynchronous to the AHB clock of the ERTEC 200. For this reason, it is synchronized with the AHB clock. The following figures show different read- and write sequences with the timings: Copyright © Siemens AG 2007. All rights reserved. Technical data subject to change...

    The ERTEC 200 generates 2 interrupt signals, LBU_IRQ0_N and LBU_IRQ1_N, to the external host. Both interrupts are generated in the IRT switch interrupt controller. Both signals are set by default to Low Active. However, they can also be assigned different parameters in the IRT switch.

  • Page 91: 10 Memory Description

    Only the ARM946E-S can access both address areas. IRT accesses to its own KRAM do not use the AHB bus. These accesses are implemented in the IRT switch controller. The KRAM can be addressed starting from the memory area 0x1010_0000. An access in the non-permissible register area is detected by an IRT-internal error signal and not by an AHB acknowledgement time-out error.
