Identifier Parity
Examples:
If the fractional baud rate is not used, the accuracy of the synchronization becomes much lower.
When the counter is stopped, the 16 most significant bits of the counter (value divided by 8)
gives the new clock divider (CD). This value is rounded by adding the first insignificant bit. The
equation of the Baudrate deviation is the same as given above, but the constants are as follows:
It follows from that, a minimum value for the nominal clock frequency:
Examples:
A protected identifier consists of two sub-fields; the identifier and the identifier parity. Bits 0 to 5
are assigned to the identifier and bits 6 and 7 are assigned to the parity.
The USART interface can generate/check these parity bits, but this feature can also be disabled.
The user can choose between two modes by the PARDIS bit of the LIN Mode register (LINMR):
During header transmission, the parity bits are computed and sent with the 6 least significant
bits of the IDCHR field of the LIN Identifier register (LINIR). The bits 6 and 7 of this register are
discarded.
During header reception, the parity bits of the identifier are checked. If the parity bits are wrong,
an Identifier Parity error occurs (see
IDCHR field are updated with the received Identifier. The bits 6 and 7 are stuck at 0.
During header transmission, all the bits of the IDCHR field of the LIN Identifier register (LINIR)
are sent on the bus.
During header reception, all the bits of the IDCHR field are updated with the received Identifier.
