External clock (XCK)
External clocking is used by the synchronous or SPI slave modes of operation. External clock input
from the XCK pin is sampled by a synchronization logic to remove meta-stability. The output from the
synchronization logic must then pass through an edge detector before it can be used by the Transmitter
and Receiver.
This process introduces a two CPU clock period delay and the maximum frequency of the external XCK
pin is limited by the following equation:
fXCK =
fSCLK
4
, where fXCK is frequency of XCK, and fSCLK is frequency of main system clock (SCLK).
