Notes:
bit 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.
bit 13: DOUT
FEN = 0, FIFO is enabled.
FEN = 1, FIFO is disabled.
bit 12: DOUT
SHDNo = 1, Software shutdown is enabled.
SHDNo = 0, Software shutdown is disabled.
bit 11: DOUT
TM = 1, Transmit buffer empty interrupt is enabled.
TM = 0, Transmit buffer empty interrupt is disabled.
bit 10: DOUT
RM = 1, Data available in the receive register or FIFO interrupt
is enabled.
RM = 0, Data available in the receive register or FIFO interrupt
is disabled.
bit 9: DOUT
PM = 1, Parity bit high received interrupt is enabled.
PM = 0, Parity bit received interrupt is disabled.
bit 8: DOUT
RAM = 1, Receiver-activity (shutdown mode)/Framing-error
(normal operation) interrupt is enabled.
RAM = 0, Receiver-activity (shutdown mode)/Framing-error
(normal operation) interrupt is disabled.
bit 7: DOUT
IR = 1, IrDA mode is enabled.
IR = 0, IrDA mode is disabled.
bit 6: DOUT
ST = 1, Transmit two stop-bits.
ST = 0, Transmit one stop-bit.
bit 5: DOUT
PE = 1, Parity is enabled for both transmit (state of Pt) and
receive.
PE = 0, Parity is disabled for both transmit and receive.
bit 4: DOUT
L = 1, 7-bit words (8-bit words if PE = 1)
L = 0, 8-bit words (9-bit words if PE = 1)
bits 3–0: DOUT
B3–B0 = XXXX Baud-Rate Divisor Select Bits (see Table 6)
Table 3. Read Configuration (D15, D14 = 0, 1)
D15 is present at DOUT on CS’s falling edge. Consecutive bits are clocked out on SCLK’s falling edge.
