Description

SC_UARTTXIDLE

[6]

This bit is set when both the transmit FIFO and the transmit serializer are empty.

SC_UARTPARERR

[5]

This bit is set when the byte in the data register was received with a parity error. This

bit is updated when the data register is read, and is cleared if the receive FIFO is

empty.

SC_UARTFRMERR

[4]

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.

SC_UARTRXOVF

[3]

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 regis-

ter.

SC_UARTTXFREE

[2]

This bit is set when the transmit FIFO has space for at least one byte.

SC_UARTRXVAL

[1]

This bit is set when the receive FIFO contains at least one byte.

SC_UARTCTS

[0]

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.
