Electrical and Thermal Characteristics
window at the internal receiving latches. This delayed clock is used to capture the data into these latches
which comprise the receive FIFO. This clock is asynchronous to all other processor clocks. This latched
data is subsequently read out of the FIFO synchronously to the processor clock. The time between writing
and reading the data is set by the using the sample point settings defined in the L3CR register.
