Data Sheet
• Change the clock source back
• 5 NOP instructions
Note: The NOPs are necessary to ensure to have time to change the frequency while
4.6
The input clock of the Analog Front End is a 4 MHz clock signal that is generated by a
dedicated divider. If enabled (PIDDHWCFG.ACT = 1), the clock tracking unit takes care
that the AFE clock is always synchronous to the frame synchronization provided by the
interface to the IOM-2 handler.
4.7
The INCA-D operates as clock master and the transmit and receive bit clocks are
derived, with the help of the Adjust Unit, from the DASL interface receive data stream.
The received signal is sampled several times inside the derived receive clock period, and
a majority logic is used to additionally reduce bit error rate in severe conditions.
IThe FSC, DCL and BCL clocks are summarized below with the respective duty cycles.
FSC 8 kHz
BCL 768 kHz1:1
DCL 1536 kHz1:1
For further details refer to the IOM-2 handler module description.
the device is running at a much higher frequency as it will be after the change. The
minimum frequency for a proper USB operation is 12 MHz.
