* console. Its purpose is to get the console output availabe as soon
|

* as possible.
|
||||
*
|
||||
* The USART0/2/3 and UART1 peripherals are configured using the following registers:
|
||||
* 1. Power: In the PCONP register, set bits PCUSART0/1/2/3.
|
||||
* On reset, USART0 and UART 1 are enabled (PCUSART0 = 1 and PCUART1 = 1)
|
||||
* and USART2/3 are disabled (PCUART1 = 0 and PCUSART3 = 0).
|
||||
* 2. Peripheral clock: In the PCLKSEL0 register, select PCLK_USART0 and
|
||||
* PCLK_UART1; in the PCLKSEL1 register, select PCLK_USART2 and PCLK_USART3.
|
||||
* 3. Baud rate: In the LCR register, set bit DLAB = 1. This enables access
|
||||
* to registers DLL and DLM for setting the baud rate. Also, if needed,
|
||||
* set the fractional baud rate in the fractional divider
|
||||
* 4. UART FIFO: Use bit FIFO enable (bit 0) in FCR register to
|
||||
* enable FIFO.
|
||||
* 5. Pins: Select UART pins through the PINSEL registers and pin modes
|
||||
* through the PINMODE registers. UART receive pins should not have
|
||||
* pull-down resistors enabled.
|
||||
* 6. Interrupts: To enable UART interrupts set bit DLAB = 0 in the LCRF
|
||||
* register. This enables access to IER. Interrupts are enabled
|
||||
* in the NVIC using the appropriate Interrupt Set Enable register.
|
||||
* 7. DMA: UART transmit and receive functions can operate with the
|
||||
* GPDMA controller.
