LIN PRESCALER FRACTION REGISTER
(LPFR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:4 = Reserved.
Bits 3:0 = LPFR[3:0] Fraction of LDIV
These 4 bits define the fraction of the LIN Divider
(LDIV):
1. When initializing LDIV, the LPFR register must
be written first. Then, the write to the LPR register

will effectively update LDIV and so the clock gen-

2. In LIN Slave mode, if the LPR[7:0] register is
Examples of LDIV coding:
Example 1: LPR = 27d and LPFR = 12d
This leads to:
Mantissa (LDIV) = 27d
Fraction (LDIV) = 12/16 = 0.75d
Therefore LDIV = 27.75d
Example 2: LDIV = 25.62d
This leads to:
LPFR = rounded(16*0.62d)
= rounded(9.92d) = 10d = Ah
LPR = mantissa (25.620d) = 25d = 1Bh
Example 3: LDIV = 25.99d
This leads to:
LPFR = rounded(16*0.99d)
= rounded(15.84d) = 16d
equal to 00h, the transceiver and receiver input
clocks are switched off.
