Overrun Error Status (Default: 0)
This bit is immediately set to “1” when an overrun error is detected. This bit
is cleared when a “0” is written.
CTS Terminal Status (Default: 0)
This field indicates the status of the CTS signal.
1: The CTS signal is High.
0: The CTS signal is Low.
Receive Break (Default: 0)
This bit is set when a break is detected. This bit is automatically cleared
when a frame that is not a break is received.
1: Current status is Break.
0: Current status is not Break.
Transmit Ready (Default: 1)
This bit is set to “1” if at least one stage in the Transmit FIFO is free.
Transmit All Sent (Default: 1)
This bit is set to “1” if the Transmit FIFO and all transmission shift registers
are empty.
UART Break Detect (Default: 0)
This bit is set when a break is detected. Once set, this bit remains set until
cleared by writing a “0” to it.
