This bit is set by hardware when receipted frame ID parity is not correct.
0 = No active.
1 = Receipted frame ID parity is not correct.
Note1:
This bit is read only, but it can be cleared by writing 1 to it.
Note2:
This bit is only valid when in LIN slave mode (SLVEN (UART_LINCTL [0])= 1) and
enable LIN frame ID parity check function IDPEN (UART_LINCTL [9]).

SLVHEF
LIN Slave Header Error Flag (Read Only)
This bit is set by hardware when a LIN header error is detected in LIN slave mode and be
cleared by writing 1 to it. The header errors include “break delimiter is too short (less than
0.5 bit time)”, “frame error in sync field or Identifier field”, “sync field data is not 0x55 in
Non-Automatic Resynchronizati
on mode”, “sync field deviation error with Automatic
Resynchronization mode”, “sync field measure time-out with Automatic Resynchronization
mode” and “LIN header reception time-out”.
0 = LIN header error not detected.
1 = LIN header error detected.
Note1:
This bit is read only, but it can be cleared by writing 1 to it.
Note2:
This bit is only valid when UART is operated in LIN slave mode (SLVEN
(UART_LINCTL [0]) = 1) and enables LIN slave header detection function (SLVHDEN
(UART_LINCTL [1])).

SLVHDETF
LIN Slave Header Detection Flag (Read Only))
This bit is set by hardware when a LIN header is detected in LIN slave mode and be
cleared by writing 1 to it.
0 = LIN header not detected.
1 = LIN header detected (break + sync + frame ID).
Note1:
This bit is read only, but it can be cleared by writing 1 to it.
Note2:
This bit is only valid when in LIN slave mode (SLVEN (UART_LINCTL [0]) = 1) and
enable LIN slave header detection function (SLVHDEN (UART_LINCTL [1])).
Note3:
When enable ID parity check IDPEN (UART_LINCTL [9]), if hardware detect
complete header (“break + sync + frame ID”), the SLVHDETF will be set whether the
frame ID correct or not.
