Example 1: To have a Bit rate of 500Kbps with a frequency of fclk = 32MHz it is possible to set:
BRP = 1, TSEG1 = 11, TSEG2 = 4.
Then the configuration to write is BCR1 = H'A300 and BCR0 = H'0001.
Example 2: To have a Bit rate of 500Kbps with a frequency of fclk = 20MHz it is possible to set:
BPR = 1, TSEG1 = 6, TSEG2 = 3.
Then the configuration to write is BCR1 = H'5200 and BCR0 = 0001.
