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
TXC(SCKT pin) = transmit clock
RXC(SCKR pin) = receive clock
FST(FST pin) = transmit frame sync
FSR(FSR pin) = receive frame sync
HCKT(HCKT pin) = transmit high speed clock
HCKR(HCKR pin) = receive high speed clock
For the internal clock, the external clock cycle is defined by Icyc and the ESAI control register.
The word-relative frame sync signal waveform relative to the clock operates in the same manner as the
bit-length frame sync signal waveform, but spreads from one serial clock before first bit clock (same as bit
length frame sync signal), until the one before last bit clock of the first word in frame.
Periodically sampled and not 100% tested
CC
(asynchronous implies that TXC and RXC are two different clocks)
(synchronous implies that TXC and RXC are the same clock)
= 3.16 V
