Example 1: To have a Bit rate of 500Kbps with a frequency of fclk = 24MHz it is possible to set:
BRP = 1, TSEG1 = 6, TSEG2 = 5.
Then the configuration to write is BCR1 = H'5400 and BCR0 = H'0001.
Example 2: To have a Bit rate of 500Kbps with a frequency of fclk = 36MHz it is possible to set:
BRP = 1, TSEG1 = 10, TSEG2 = 7.
Then the configuration to write is BCR1 = H'9600 and BCR0 = H'0001.
