|Registers / SYSCON Register description|
All USART peripherals share a common clock U_PCLK, which can be adjusted by a fractional divider:
U_PCLK = UARTCLKDIV/(1 + MULT/DIV).
UARTCLKDIV is the USART clock configured in the UARTCLKDIV register.
The fractional portion (1 + MULT/DIV) is determined by the two USART fractional divider registers in the SYSCON block:
|7:0||DIV||Denominator of the fractional divider. DIV is equal to the programmed value +1. Always set to 0xFF to use with the fractional baud rate generator.||0|
