(1) Baud rate calculation expression
The baud rate for UART (UART0 to UART4) communication can be calculated by the following expressions.
The operation clock (f
mode register mn (SMRmn).
(Baud rate) = {Operation clock (f
Caution Setting serial data register mn (SDRmn) SDRmn[15:9] = (0000000B, 0000001B) is prohibited.
Remarks 1.
2.
When UART is used, the value of SDRmn[15:9] is the value of bits 15 to 9 of the SDRmn
register (0000010B to 1111111B) and therefore is 2 to 127.
