Time Quanta (TQ) is an integer multiple of the number of system clocks, and is determined by the
baud rate prescaler (BRP) as follows. f
The following formula is used to calculate the 1-bit time and bit rate.
Note: f
Example: With φ = 40 MHz, BRP = B'000001 (2TQ), TSEG1 = B'0100 (5TQ), and TSEG2 =

(BCR[15:12])
TSEG1
The TQ value of BCR is used for BRP, TSEG1, and TSEG2.
*
CLK
TQ = (BRP setting + 1)/f
1-bit time = TQ × (1 + TSEG1 + TSEG2)
Bit rate = 1/Bit time
B'011 (4TQ):
Bit rate = 20/{(2) × (1 + 5 + 4)} = 1 Mbps
When BRP[7:0] are B'00000000, TSEG[2:0] should not be set to B'001.
