MODEM_IF
RLS_IF
THRE_IF
RDA_IF
MODEM Interrupt Flag (Read Only)
This bit is set when the CTS pin has state change (DCTSF=1). If UA_IER
[MODEM_IEN] is enabled, the Modem interrupt will be generated.
NOTE: Write 1 to clear this bit to zero.
Receive Line Interrupt Flag (Read Only).
This bit is set when the RX receive data have parity error, framing error or break error
(at least one of 3 bits, BIF, FEF and PEF, is set). If UA_IER [RLS_IEN] is enabled,
the RLS interrupt will be generated.
NOTE: When in RS-485 function mode, this field include “receiver detect any
address byte received address byte character (bit9 = ‘1’) bit.
NOTE: Write 1 to clear this bit to zero.
Transmit Holding Register Empty Interrupt Flag (Read Only).
This bit is set when the last data of TX FIFO is transferred to Transmitter Shift
Register. If UA_IER [THRE_IEN] is enabled, the THRE interrupt will be generated.
NOTE: This bit is read only and it will be cleared when writing data into THR (TX
FIFO not empty).
Receive Data Available Interrupt Flag (Read Only).
When the number of bytes in the RX FIFO equals the RFITL then the RDA_IF will be
set. If UA_IER [RDA_IEN] is enabled, the RDA interrupt will be generated.
NOTE: This bit is read only and it will be cleared when the number of unread bytes of
RX FIFO drops below the threshold level (RFITL).
