Register 12: UART Masked Interrupt Status (UARTMIS), offset 0x040
The UARTMIS register is the masked interrupt status register. On a read, this register gives the
current masked status value of the corresponding interrupt. A write has no effect.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
LIN Mode Edge 5 Masked Interrupt Status
Value Description
1 An unmasked interrupt was signaled due to the 5th falling edge
of the LIN Sync Field.
0 An interrupt has not occurred or is masked.
This bit is cleared by writing a 1 to the LME5IC bit in the UARTICR
register.
LIN Mode Edge 1 Masked Interrupt Status
Value Description
1 An unmasked interrupt was signaled due to the 1st falling edge
of the LIN Sync Field.
0 An interrupt has not occurred or is masked.
This bit is cleared by writing a 1 to the LME1IC bit in the UARTICR
register.
