assertion
1. V
2. SCKT(SCKT pin) = transmit clock
3. bl = bit length
4. i ck = internal clock
5. For the internal clock, the external clock cycle is defined by Icyc and the ESAI control register.
6. The word-relative frame sync signal waveform relative to the clock operates in the same manner as the bit-length frame sync signal
7. Periodically sampled and not 100% tested
8. ESAI_1 specs match those of ESAI_0
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
wl = word length
wr = word length relative
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)
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.
