BIT_ERR_F
Bit Error Detect Status Flag (Read Only)
At TX transfer state, hardware will monitoring the bus state, if the input pin (SIN) state not
equals to the output pin (SOUT) state, BIT_ERR_F (UA_LIN_SR[9]) will be set.
When occur bit error, if the LIN_IEN (UA_IER[8]) = 1, an interrupt will be generated.
Note1:
This bit is read only, but it can be cleared by writing 1 to it.
Note2:
This bit is only valid when enable bit error detection function (BIT_ERR_EN
(UA_LIN_CTL [12]) = 1).
[8]
LIN_BKDET_F
LIN Break Detection Flag (Read Only)
This bit is set by hardware when a break is detected and be cleared by writing 1 to it
through software.
0 = LIN break not detected.
1 = LIN break detected.
Note1:
This bit is read only, but it can be cleared by writing 1 to it.
Note2:
This bit is only valid when LIN break detection function is enabled
(LIN_BKDET_EN (UA_LIN_CTL[10]) =1).

LINS_SYNC_F
LIN Slave Sync Field
This bit indicates that the LIN sync field is being analyzed in Automatic Resynchronization
mode. When the receiver header have some error been detect, user must reset the
internal circuit to re-search new frame header by writing 1 to this bit.
0 = The current character is not at LIN sync state.
1 = The current character is at LIN sync state.
Note1:
This bit is only valid when in LIN Slave mode (LINS_EN(UA_LIN_CTL[0]) = 1).
Note2:
This bit is read only, but it can be cleared by writing 1 to it.
Note3:
When writing 1 to it, hardware will reload the initial baud rate and re-search a new
