Field Description
0:15 Reserved
SZF
16
Stuck at Zero Flag
This bit is set by hardware when the bus is dominant for more than a 100-bit time. It is cleared by
software.
OCF
17
OCF Output Compare Flag
0 No output compare event occurred.
1 The content of the counter has matched the content of OC1[0:7] or OC2[0:7] in LINOCR.
An interrupt is generated if the OCIE bit in LINIER register is set.
PE3
18
Parity Error Flag Rx3
This bit indicates if there is a parity error in the corresponding received byte (Rx3). See
Section 23.8.1.1, Buffer in UART mode. No interrupt is generated if this error occurs.
0 No parity error.
1 Parity error.
PE2
19
Parity Error Flag Rx2
This bit indicates if there is a parity error in the corresponding received byte (Rx2). See
Section 23.8.1.1, Buffer in UART mode. No interrupt is generated if this error occurs.
0 No parity error.
1 Parity error.
PE1
20
Parity Error Flag Rx1
This bit indicates if there is a parity error in the corresponding received byte (Rx1). See
Section 23.8.1.1, Buffer in UART mode. No interrupt is generated if this error occurs.
0 No parity error.
1 Parity error.
PE0
21
Parity Error Flag Rx0
This bit indicates if there is a parity error in the corresponding received byte (Rx0). See
Section 23.8.1.1, Buffer in UART mode. No interrupt is generated if this error occurs.
0 No parity error.
1 Parity error.
