LIN fractional baud rate register (LINFBRR)
Table 245. LINTOCR field descriptions
Field Description
RTO
Response timeout value
This field contains the response timeout duration (in bit time) for 1 byte.
The reset value is 0xE = 14, corresponding to T
Response_Maximum
=1.4×T
Response_Nominal
HTO
Header timeout value
This field contains the header timeout duration (in bit time). This value does not include the
Break and the Break Delimiter. The reset value is the 0x2C = 44, corresponding to
T
Header_Maximum.
Programming LINSR[MME] = 1 changes the HTO value to 0x1C = 28.
This field can be written only in Slave mode.

Table 246. LINFBRR field descriptions
Field Description
DIV_F
Fraction bits of LFDIV
The 4 fraction bits define the value of the fraction of the LINFlex divider (LFDIV).
Fraction (LFDIV) = Decimal value of DIV_F / 16.
This field can be written in Initialization mode only.
