SC_UARTFRMERR
This bit is set when both the transmit FIFO and the transmit serializer are empty.
This bit is set when the byte in the data register was received with a parity error. This bit
This bit is set when the transmit FIFO has space for at least one byte.
Description
is updated when the data register is read, and is cleared if the receive FIFO is empty.
This bit is set when the byte in the data register was received with a frame error. This bit
is updated when the data register is read, and is cleared if the receive FIFO is empty.
This bit is set when the receive FIFO has been overrun. This occurs if a byte is received
when the receive FIFO is full. This bit is cleared by reading the data register.
This bit is set when the receive FIFO contains at least one byte.
This bit shows the logical state (not voltage level) of the nCTS input:
0: nCTS is deasserted (pin is high, 'XOFF', RS232 negative voltage); the UART is inhibited
from starting to transmit a byte.
1: nCTS is asserted (pin is low, 'XON', RS232 positive voltage); the UART may transmit.
