BUF_ERR_IF
TOUT_IF
MODEM_IF
RLS_IF
1 = The Tout interrupt is generated
0 = No Tout interrupt is generated
MODEM Status Interrupt Indicator (Read Only). (not available in UART2 channel)
This bit is set if MODEM_IEN and MODEM_IF are both set to 1.
1 = The Modem interrupt is generated
0 = No Modem interrupt is generated
Receive Line Status Interrupt Indicator (Read Only).
This bit is set if RLS_IEN and RLS_IF are both set to 1.
1 = The RLS interrupt is generated
0 = No RLS interrupt is generated
Transmit Holding Register Empty Interrupt Indicator (Read Only).
This bit is set if THRE_IEN and THRE_IF are both set to 1.
1 = The THRE interrupt is generated
0 = No THRE interrupt is generated
Receive Data Available Interrupt Indicator (Read Only).
This bit is set if RDA_IEN and RDA_IF are both set to 1.
1 = The RDA interrupt is generated
0 = No RDA interrupt is generated
LIN Bus RX Break Field Detected Flag (Read Only)
This bit is set when RX received LIN Break Field. If UA_IER [LIN_RX_BRK_IEN] is
enabled the LIN RX Break interrupt will be generated.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
Reserved
Buffer Error Interrupt Flag (Read Only)
This bit is set when the TX or RX FIFO overflows (TX_OVER_IF or RX_OVER_IF is
set). When BUF_ERR_IF is set, the transfer maybe is not correct. If UA_IER
[BUF_ERR_IEN] is enabled, the buffer error interrupt will be generated.
Note: This bit is cleared when both TX_OVER_IF and RX_OVER_IF are cleared.
Time Out Interrupt Flag (Read Only)
This bit is set when the RX FIFO is not empty and no activities occurred in the RX
FIFO and the time out counter equal to TOIC. If UA_IER [TOUT_IEN] is enabled, the
Tout interrupt will be generated.
Note: This bit is read only and user can read UA_RBR (RX is in active) to clear it.
MODEM Interrupt Flag (Read Only) (not available in UART2 channel)
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: This bit is read only and reset to 0 when bit DCTSF is cleared by a write 1 on
DCTSF.
Receive Line Interrupt Flag (Read Only). (Low Density 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".
