Table 7.
When using the motor control connector, ensure that JP9 is set to allow the use of P0.1 on
the STR910F for motor control. JP9 can be configured to use P0.1 for the USB peripheral.

RTC and tamper
A 32KHz crystal X2 is available for the embedded RTC inside the STR91xF. The push
button PB1 can be used to simulate a tamper event on the RTC.
USB
The STR910-EVAL evaluation board offers USB 2.0 compliant communication via a USB
type-B connector (CN3) with full-speed (12Mb/s) data transfer. The evaluation board and
daughter board can be powered from this USB connection at 5V DC with a 500mA current
limitation.
Two clock sources are available for USB:
●
●
Clock source is selected by setting JP17. Refer to
configuration details.
The unplugging of hardware from the USB connector (CN3) can be simulated by your
application software. USB hardware disconnect simulation is enabled by configuring the
jumper JP9, as described in
Table 8.

STR91xF I/O pin P25 is used as external clock of timer for motor control when JP8 is
fitted. P25 can be used by a daughter board when JP8 is not fitted.
Default setting: Fitted
JP9 can be used to enable USB hardware disconnect simulation using P0.1 on the
STR910F. P0.1 of the STR91xF can be used either for Motor Control or USB.
USB hardware disconnect simulation is enabled and P0.1 of the
STR910F is used by the USB peripheral when JP9 is set as
shown to the right:
In this case, the USB pull up resistor (R10) is connected to pin 3
of the USB connector.
USB hardware disconnect simulation is disabled, and P0.1 of
the STR910F is used by the Motor Control connector (C1) when
JP9 is set as shown to the right:
