4.6.2 UART Data Interface
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms to RS-232 interface protocol. The UART can be used as a serial data port
in Mobile Station testing and debugging with a properly written, user-defined download program.
All communication between the microprocessor and the UART goes through the microprocessor
interface. The microprocessor interface synchronizes the data and command signals to the UART.
