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. 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 application note PCB Design with an
SN260 (120-5047-000) for the PCB-level design details regarding the implementation of the
SIF interface.
The SN260 pins involved in the SIF Interface:
●
●
●
●
●
In addition, the VDD_PADS and Ground Net are required for external voltage translation and
buffering of the SIF Signals.
The SIF interface provides the following:
●
●
In order to achieve the deep sleep currents specified in Table 5, a pull-down resistor must be
connected to the SIF_MOSI pin. In addition, Ember recommends a pull-up resistor to be
placed on the nSIF_LOAD pin in order to prevent noise from coupling onto the signal. Both
of these recommendations are documented within the SN260 Reference designs.
When developing application-specific manufacturing test procedures, Ember recommends
the designer refer to Manufacturing Test Guidelines (120-5016-000). This document
provides more detail regarding importance of designing the proper SIF interface as well as
timing of the SIF.
