SPI/MICROWIRE-Compatible UART and ±15kV ESD-
Protected RS-232 Transceivers with Internal Capacitors
Table 4. Write Data (D15, D14 = 1, 0)
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.
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.
bits 15, 14: DIN
1, 0 = Write Data
bits 13–11: DIN
Zeros
bit 10: DIN
TE = 1, Disables transmit and only RTS will be updated.
TE = 0, Enables transmit.
bit 9: DIN
RTS = 1, Configures RTS = 0 (logic low).
RTS = 0, Configures RTS = 1 (logic high).
bit 8: DIN
Pt = 1, Transmit parity bit is high. If PE = 1, a high parity bit will
be transmitted. If PE = 0, then no parity bit will be transmitted.
Pt = 0, Transmit parity bit is low. If PE = 1, a low parity bit will be
transmitted. If PE = 0, then no parity bit will be transmitted.
bits 7–0: DIN
D7t–D0t = Transmitting Data Bits. D7t is ignored when L = 1.
D15 is present at DOUT on CS’s falling edge. Consecutive bits are clocked out on SCLK’s falling edge.
