Character transmitted (0 to 1 transition of
Character received (0 to 1 transition of
Received and lost character while receive FIFO was full (Receive overrun error)
Transmitted character while transmit FIFO was empty (Transmit underrun error)
Registers
Transmit and receive data register. Writing to this register pushes a byte onto the transmit
FIFO. Reading from this register pulls a byte from the receive FIFO.
SC1 Mode: 0 = disabled; 1 = UART mode; 2 = SPI mode; 3 = I2C mode. NOTE: To change be-
tween modes, the previous mode must be disabled first.
The baud rate period (N) of the clock rate as seen in the equation: rate = 24MHz / ( 2 * ( N +
(0.5*F) ) )
