For the internal clock, the external clock cycle is defined by the instruction cycle time (timing 7 in Table 2-5 on page 2-4) and the
ESSI control register. T

The word-length-relative frame sync signal waveform operates the same way as the bit-length frame sync signal waveform, but
spreads from one serial clock before the first bit clock (same as the Bit Length Frame Sync signal) until the one before last bit
clock of the first word in the frame.
Periodically sampled and not 100 percent tested
V
TXC (SCK Pin) = Transmit Clock
RXC (SC0 or SCK Pin) = Receive Clock
FST (SC2 Pin) = Transmit Frame Sync
FSR (SC1 or SC2 Pin) Receive Frame Sync
i ck = Internal Clock; x ck = External Clock
i ck a = Internal Clock, Asynchronous Mode (asynchronous implies that TXC and RXC are two different clocks)
i ck s = Internal Clock, Synchronous Mode (synchronous implies that TXC and RXC are the same clock)
In the timing diagrams below, the clocks and frame sync signals are drawn using the clock falling edge as a the first reference.
Clock and frame sync polarities are programmable in Control Register B (CRB). Refer to the DSP56321 Reference Manual for
details.
