R/W = 0; A[3:0] = register address; CH1 = 0, CH0 = 0
a. Register write
R/W = 1; A[3:0] = register address; CH1 = 0, CH0 = 0
b. Register read
R/W = 0; A[3:0] = 0000; CH1 = 0, CH0 = 0
c. FIFO write cycle
R/W = 1; A[3:0] = 0000; CH1 = 0, CH0 = 0
d. FIFO read cycle
(1) Last bit (D0) of the last byte to be written to the transmit FIFO.
(2) Last bit (D0) of the last byte to be read from the receive FIFO.
