1 i ck = internal clock

x ck = external clock

i ck a = internal clock, asynchronous mode

(asynchronous implies that SCKT and SCKR are two different clocks)

i ck s = internal clock, synchronous mode

(synchronous implies that SCKT and SCKR are the same clock)

2 bl = bit length

wl = word length

wr = word length relative

3 SCKT(SCKT pin) = transmit clock

SCKR(SCKR pin) = receive clock

FST(FST pin) = transmit frame sync

FSR(FSR pin) = receive frame sync

HCKT(HCKT pin) = transmit high frequency clock

HCKR(HCKR pin) = receive high frequency clock

4 For the internal clock, the external clock cycle is defined by Icyc and the ESAI control register.

5 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 it spreads from one serial clock before the first bit clock (like the bit length frame sync signal), until the

second-to-last bit clock of the first word in the frame.

6 Periodically sampled and not 100% tested.
