UART and UART1
The XC886/888 provides two Universal Asynchronous Receiver/Transmitter (UART and
UART1) modules for full-duplex asynchronous reception/transmission. Both are also
receive-buffered, i.e., they can commence reception of a second byte before a
previously received byte has been read from the receive register. However, if the first
byte still has not been read by the time reception of the second byte is complete, one of
the bytes will be lost.
Features:
Full-duplex asynchronous modes
– 8-bit or 9-bit data frames, LSB first
– fixed or variable baud rate
Receive buffered
Multiprocessor communication
Interrupt generation on the completion of a data transmission or reception
The UART modules can operate in four asynchronous modes as shown in
Table 28
.
Data is transmitted on TXD and received on RXD.
Table 28
Operating Mode
Mode 0: 8-bit shift register
Mode 1: 8-bit shift UART
Mode 2: 9-bit shift UART
Mode 3: 9-bit shift UART
There are several ways to generate the baud rate clock for the serial port, depending on
the mode in which it is operating. In mode 0, the baud rate for the transfer is fixed at
f
PCLK
/2. In mode 2, the baud rate is generated internally based on the UART input clock
and can be configured to either f
PCLK
/32 or f
PCLK
/64. For UART1 module, only f
PCLK
/64
is available. The variable baud rate is set by the underflow rate on the dedicated baud-
rate generator. For UART module, the variable baud rate alternatively can be set by the
overflow rate on Timer 1.
