Notes:
bits 15: DOUT
R = 1, Data is available to be read or is being read from the
receive register or FIFO.
R = 0, Receive register and FIFO are empty.
bit 14: DOUT
T = 1, Transmit buffer is empty.
T = 0, Transmit buffer is full.
bits 13–11: DOUT
Zeros
bit 10: DOUT
RA/FE = Receive-Activity (UART shutdown)/Framing-Error
(Normal Operation) Bit
bit 9: DOUT
CTS = CTS input state. If CTS = 0, then CTS = 1 and vice versa.
bit 8: DOUT
Pr = Received parity bit. This is only valid if PE = 1.
bits 7–0: DOUT
D7r–D0r = Received Data Bits. D7r = 0 for L = 1.
Table 5. Read Data (D15, D14 = 0, 0)
D15 is present at DOUT on CS’s falling edge. Consecutive bits are clocked out on SCLK’s falling edge.
