Serial Microcontroller Interface Read Access
Programming the Microcontroller Interface Without Clocks at FSC, MCLK, PCLK
The SLICOFI-2x can also be programmed via the
C interface without any clocks
connected to the FSC, MCLK, PCLK pins. This can be useful in Power Down modes
when further power saving on system level is necessary. In this case a data clock of up
to 1.024 MHz can be used on pin DCLK.
Since the SLICOFI-2x will leave the basic reset routine only if clocks at the FSC, MCLK
and PCLK pins are applied, it is not possible to program the SLICOFI-2x without any
clocks at these pins directly after the hardware reset or power on reset.
