Description
Framing Error. When active, this bit indicates a stop bit was
missing from the serial transmission string. Cleared on next
transmission. [0]
Parity Error. When active, this bit indicates the serial
transmission was received with the incorrect parity. Cleared
on next transmission. [0]
Discrete Input 2. This bit reflects the input stimulus applied
to the input pin.
UART Transmitter Buffer Empty. This bit indicates the
Transmitter Buffer Register is empty and ready for data. [0]
UART Transmitter Empty. This bit is low while the UART
is transmitting data and goes high when the transmission is
complete. [0]
UART Data Ready. This active-high signal indicates the
UART received a serial data word and this data is available.
Cleared on the execution of INR Rd, RCVR. [0]
UART Receiver Register (RCVR)
The UART Receiver Buffer Register (see figure 7) receives
9600-baud asynchronous serial data through the UARTIN
input pin on the UT69R000. Each serial data string contains an
active-low Start bit, eight Data bits, an odd Parity bit, and an
active-high Stop bit. Figure 8 shows a single serial data string.
While receiving a serial data string, the UT69R000 generates
four status flags: Data Ready (DR), Overrun Error (OE),
Framing Error (FE), and Parity Error (PE). The UT69R000
stores these bits in the System Status Register.
Receiver buffer register bits 15-8 are always low. Bit numbers,
7 to 0 (RCD7 - RCD0) contain data the UT69R000 receives
via the serial data port. RCD7 is the MSB; RCD0 is the LSB.
