Clock source
Four clock sources are available on the STR910-EVAL evaluation board for the
microcontroller, USB, RTC and Ethernet PHY transceiver.

USB and Ethernet PHY are also able to run using the clock from the STR91xF. The clock
system can be configured by setting the jumpers JP25 and JP17 as described in

X1– 25MHz crystal for STR91xF microcontroller
X2– 32KHz crystal for embedded RTC
X3– 25MHz crystal for Ethernet PHY transceiver U15
U12– 48MHz oscillator for USB
Selects one of the three possible 5V DC power supply sources:
For Power supply jack (CN2) to the STR910-EVAL only, JP6 is
set as shown to the right:
(Default setting)
For Power supply jack (CN2) to both STR910-EVAL evaluation
board and a daughter board connected to CN5 and CN6, JP6 is
set as shown to the right:
For power supply from the daughter board connectors (CN5
and CN6), JP6 is set as shown to the right:
For power supply from USB (CN3), JP6 is set as shown to the
right:
If a daughter board is connected on CN5 and CN6, it must not
have its own power supply connected. The USB connection
supplies power to both the STR910-EVAL evaluation board and
the daughter board.
Enables consumption measurement of 3.3V STR91xF I/O power supply (VDDQ).
Default setting: Fitted
Enables consumption measurement of 1.8V STR91xF CPU core power supply.
Default setting: Fitted
Enables consumption measurement of STR91xF analog power supply (AVDD).
Default setting: Fitted
Enables consumption measurement of STR91xF backup power supply (VBAT).
Default setting: Fitted
