Register 4: UART Integer Baud-Rate Divisor (UARTIBRD), offset 0x024
The UARTIBRD register is the integer part of the baud-rate divisor value. All the bits are cleared
on reset. The minimum possible divide ratio is 1 (when UARTIBRD=0), in which case the
UARTFBRD register is ignored. When changing the UARTIBRD register, the new value does not
take effect until transmission/reception of the current character is complete. Any changes to the
baud-rate divisor must be followed by a write to the UARTLCRH register. See “Baud-Rate
Generation” on page 184 for configuration details.
