As shown in Figure 1.84, the CLK polarity select bit (bit 6 at addresses 03A4
lection of the polarity of the transfer clock.
As shown in Figure 1.85, when the transfer format select bit (bit 7 at addresses 03A4
“0”, the transfer format is “LSB first”; when the bit = “1”, the transfer format is “MSB first”.
