I²C Baud Rate High and Low Byte Registers
The I²C Baud Rate High and Low Byte registers combine to form a 16-bit reload value,
BRG[15:0], for the I²C Baud Rate Generator. The I²C baud rate is calculated using the fol-
lowing equation:
I2C Baud Rate (bits/s) = ^{S----y---s--t--e---m------4C-----}_×^{l-o---cB---k-R----F-G---r-[-e-1--q-5--u-:--0-e--n]----c--y-----(--H----z---)}
.
