UART hardware/software last status :-
Internal software data (key)
(DATA) : %% 1
Internal hardware registers (IREG) : %% 2
Internal hardware parameters (IRAM) : %% 3
Current channel port (UART_PORT) : %% 4
Reception data lock (RXBD_LOCK) : %% 5
Transmission data lock (TXBD_LOCK) : %% 6
Reception data header (RXBD_HEAD) : %% 7
Reception data tail (RXBD_TAIL) : %% 8

1. Device key address.
2. H-W registers address.
3. H-W parameters address.
4. The Port number.
5. Semaphore of the reception function.
6. Semaphore of the transmission function.
7. Offset for Rx descriptors for receiving frame.
8. Offset in RX_QUEUE for moving the next frame to upper layers.
9. Offset in TX_QUEUE for moving a new frame to transmission, by upper layers.
10. Offset in TX_QUEUE from where this device takes the next frame for transmission.
11. MTE signal of events that took place.
12. Whether the frame is formatted/unformatted.
13. The actual counter that counts the number of idles since the last character was received. For example,
the time that a character takes to arrive (corresponds to idle) at 9600 baud is 1 msec.
14. The number of times the parity error occurred during the reception of a single byte.
15. The number of times the framing error occurred during the reception of a single byte.
16. The number of times the noise error occurred during the reception of a single byte.
17. The number of times a break signal (end of reception) was received at the port.
