UART Programmable Baud Rate Register (UART_BAUD)
This register sets the baud rate when using programmable baud rate. The initial value of the
register is determined from the selected fixed baud rate C_UART_BAUDRATE and the clock
frequency C_FREQ, using the formula:

General Purpose Output x Register (GPOx) (x = 1, 2, 3 or 4)
This register holds the value that will be driven to the corresponding bits in the I/O Module
GPOx port output signals. All bits in the register are updated when the register is written.
This register is not implemented if the value of C_USE_GPOx is 0.

General Purpose Input x Register (GPIx) (x=1, 2, 3 or 4)
This register reads the value that is input on the corresponding I/O Module GPIx port input
signal bits. This register is not implemented if the value of C_USE_GPIx is 0.
