11.4 Transfer Rate
The baud rate of UART is set of UARTCR1<BRG>. The example of the baud rate are shown as follows.
When TC3 is used as the UART transfer rate (when UARTCR1<BRG> = “110”), the transfer clock and transfer
rate are determined as follows:
Transfer clock [Hz] = TC3 source clock [Hz] / TTREG3 setting value
Transfer Rate [baud] = Transfer clock [Hz] / 16
11.5 Data Sampling Method
The UART receiver keeps sampling input using the clock selected by UARTCR1<BRG> until a start bit is
detected in RXD pin input. RT clock starts detecting “L” level of the RXD pin. Once a start bit is detected, the start
bit, data bits, stop bit(s), and parity bit are sampled at three times of RT7, RT8, and RT9 during one receiver clock
interval (RT clock). (RT0 is the position where the bit supposedly starts.) Bit is determined according to majority
rule (The data are the same twice or more out of three samplings).
