Bits Description
[31:16] Reserved Reserved.
[15] LIN_INT
LIN Bus Interrupt Indicator (Read Only)
This bit is set if LIN_RX_BRK_IEN(UA_IER[8]) and LIN_IF(UA_ISR[7]) are both set to 1.
0 = No LIN RX Break interrupt is generated.
1 = LIN RX Break interrupt is generated.
[14] Reserved Reserved.
[13] BUF_ERR_INT
Buffer Error Interrupt Indicator (Read Only)
This bit is set if BUF_ERR_IEN(UA_IER[5]) and BUF_ERR_IF(UA_ISR[5]) are both set to
1.
0 = No buffer error interrupt is generated.
1 = The buffer error interrupt is generated.
[12]
TOUT_INT
Time-out Interrupt Indicator (Read Only)
This bit is set if TIME_OUT_EN(UA_IER[11]) and TOUT_IF(UA_ISR[4]) are both set to 1.
0 = No Tout interrupt is generated.
1 = Tout interrupt is generated.
[11] MODEM_INT
MODEM Status Interrupt Indicator (Read Only)
This bit is set if MODEM_IEN(UA_IER[3]) and MODEM_IF(UA_ISR[3]) are both set to 1.
0 = No Modem interrupt is generated.
1 = Modem interrupt is generated.
[10] RLS_INT
Receive Line Status Interrupt Indicator (Read Only)
This bit is set if RLS_IEN(UA_IER[2]) and RLS_IF(UA_ISR[2]) are both set to 1.
0 = No RLS interrupt is generated.
1 = RLS interrupt is generated.
