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 SN260. Therefore, any design

implementing the SN260 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 SN260 reference design for

details regarding the implementation of the SIF interface.Go to www.stmcu.com for details.

The SIF interface provides the following:

●

IC production test (especially analog)

●

PCB production test

●

Firmware download

●

Product control and characterization

The pins are:

●

nSIF_LOAD

●

SIF_CLK

●

SIF_MOSI

●

SIF_MISO

The maximum serial shift speed for the SIF interface is 48MHz. SIF interface accesses can

be initiated even when the chip is in idle, deep sleep, or power down modes. An edge on

nSIF_LOAD wakes the chip to allow SIF cycles.
