DCLK
In Continuous mode, no interrupt is available in Stand-by mode.
See also the DMODE1:DMODE0 bits in the FTXRXIREG and FTPRIREG registers.
In Continuous mode, no interrupt is available in Stand-by mode.
Also refer the DMODE1:DMODE0 bits in the FTXRXIREG and FTPRIREG registers for details.
In Continuous mode, it is always recom-
mended to enable the bit synchronizer to
clean the DATA signal even if the DCLK
signal is not used by the Microcontroller
(bit synchronizer is automatically enabled
in Buffered and Packet mode).
