R/W = 0; A[3:0] = register address; CH[1:0] = 00 for channel A; CH[1:0] = 01 for channel B
a. Register write
R/W = 1; A[3:0] = register address; CH[1:0] = 00 for channel A; CH[1:0] = 01 for channel B
b. Register read
R/W = 0; A[3:0] = 0000; CH[1:0] = 00 for channel A; CH[1:0] = 01 for channel B
c. FIFO write cycle
R/W = 1; A[3:0] = 0000; CH[1:0] = 00 for channel A; CH[1:0] = 01 for channel B
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.
