7 SIF Module Programming and Debug Interface
SIF is a synchronous serial interface developed by Cambridge Consultants Ltd. It is the primary programming
and debug interface of the EM260. Therefore, any design implementing the EM260 should make the SIF signals
readily available. The SIF module allows external devices to read and write memory-mapped registers in real-
time without changing the functionality or timing of the XAP2b core. See the EM260 Reference Design for
details regarding the implementation of the SIF interface.
The SIF interface provides the following:
The pins are:
Because the SIF module directly connects to the program and data memory buses within the EM260, it has
access to the entire Flash and RAM blocks, as well as the on-chip registers.
The maximum serial shift speed for the SIF interface is 48MHz. SIF interface accesses can be initiated even
when the chip is in idle and deep sleep modes. An edge on nSIF_LOAD wakes the chip to allow SIF cycles.
