6.12.5.2 UART Controller Baud Rate Compensation

The ISD94100 series UART controller supports baud rate compensation function. It is used to

optimize the precision for each bit. Two examples are given below to explain the compensation

BRCOMPDEC bit (UART_BRCOMP[31])

= 0: positive compensation, increase one UART clock cycle,

= 1: negative compensation, decrease one UART clock cycle.

BRCOMP bits (UART_BRCOMP[8:0]: for each bit in BRCOMP, '1' means to do

compensation, while '0' means not to do compensation.

(1). UART's peripheral clock = 32.768K and baud rate is 9600

Baud rate is 9600, UART peripheral clock is 32.768K  3.413 peripheral clock/bit
