P4)" on page 2-23.
Example programs are included in the EZ-Board installation directory to
demonstrate UART and RS-232 operations.

RTC Interface

The ADSP-BF518F processor has a real-time clock (RTC) and a watchdog
timer. Typically, the RTC interface is used to implement a real-time
watchdog or a life counter of the time elapsed since the last system reset.
The EZ-Board is equipped with a Panasonic CR1632 lithium coin and 3V
battery supplying 125 mAh. The 3V battery and 3.3V supply of the board
connect to the
powered, the RTC circuit uses the board power to supply voltage to the
pin. When the EZ-Board is not powered, the RTC circuit uses the
RTC
lithium battery to maintain power to the
mylar, the battery lasts for about one year with the EZ-Board unpowered.
Example programs are included in the EZ-Board installation directory to
demonstrate the RTC features.
The EZ-Board is shipped with a protective Mylar sheet placed
between the coin battery and positive pin of the battery holder.
Remove the Mylar sheet before using the RTC in the processor.
