Baud Rate Discrimination between UART0 and UART1
U1T2DIS : Used to disable RCLK/TCLK control for UART1 to generate
U0T2DIS : Used to disable RCLK/TCLK control for UART0 to generate
UART0 and UART1 to different baud rates.
U0T2DIS
U1T2DIS
An user can selectively disable TCLK or RCLK to set
For instance, if U0T2DIS is set, UART0 may use Timer1
for baud rate generation even though TCLK or RCLK
bit is set.
