For the internal clock, the external clock cycle is defined by Icyc (see Timing 7) and the ESSI Control Register.
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
i ck s = Internal Clock, Synchronous mode
bl = bit length; wl = word length; wr = word length relative.
If the DSP core writes to the transmit register during the last cycle before causing an underrun error, the delay is 20 ns + (0.5
× T
An expression is used to compute the number listed as the minimum or maximum value as appropriate.

(asynchronous implies that TXC and RXC are two different clocks)
(synchronous implies that TXC and RXC are the same clock)
