The SC1 UART controller is enabled with
The UART mode contains the following features:
The following signals can be made available on GPIO pins:
The SC1 UART module obtains its reference baud-rate clock from a programmable baud generator. Baud rates
are set by a clock division ratio from the 24MHz clock:
rate = 24MHz / ( 2 * ( N + (0.5 * F) ) )
The integer portion, N, is written to the
SC1_UARTFRAC
mum allowable setting for
The UART module supports various frame formats depending upon the number of data bits (
the number of stop bits (
SC1_UART8BIT
ter. In addition, the UART module supports flow control by setting
