.

RTC Interface

The ADSP-BF526 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, 3V
battery supplying 125 mAh. The 3V battery and 3.3V supply of the board
connect to the

RTC

power pin of the processor. When the EZ-Board is

powered, the RTC circuit uses the board power to supply voltage to the

RTC

pin. When the EZ-Board is not powered, the RTC circuit uses the

lithium battery to maintain the power to the

RTC

pin. After removing 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.

For more information on the RTC and watchdog timer, refer to the

ADSP-BF52x Blackfin Processor Hardware Reference

.

LEDs and Push Buttons

The EZ-Board provides two push buttons and three LEDs for gen-
eral-purpose I/O and two additional push buttons intended for power
down and wake functionality, which also can be used as GPIO flag pins.

The three LEDs, labeled

LED0

through

LED2

, are accessed via the

PF8

,

PG11

,

and

PG12

pins of the processor (respectively). For information on how to
