Table 167. SerialSpeed bits
Bit Symbol Description
7 to 5 BR_T0 BR_T0 = 0: transfer speed = 27.12 MHz / (BR_T1 + 1)
BR_T0 > 0: transfer speed = 27.12 MHz / (BR_T1 + 33) / 2^(BR_T0  1)
4 to 0 BR_T1 BR_T0 = 0: transfer speed = 27.12 MHz / (BR_T1 + 1)
BR_T0 > 0: transfer speed = 27.12 MHz / (BR_T1 + 33) / 2^(BR_T0  1)
