2.9 Motor control
STR910-EVAL board supports induction motor control via a 34-pin connector CN1, which
provides all required control and feedback signals to and from a motor power-drive board.
Available signals on this connector include emergency stop, motor speed, 3-phase motor
current, bus voltage, Heatsink temperature from the motor drive board and 6 channels of
PWM control signals going to the motor drive circuit.
Emergency stop, motor current sampling and motor speed detection are enabled by setting
jumpers JP16, JP7 and JP8.
The potentiometer (RV2) can be used to control motor speed when JP1 is configured to
connect RV2 to P46 of the STR91xF.
Table 7. Motor control jumpers
Jumper Description
JP16
JP7
JP16 enables the emergency stop function on P67 of the motor control connector CN1.
P67 of the STR91xF is shared by both motor control and ETM trace support.

Note: 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 ca n be configured to use P0.1 for the USB peripheral.
See Table 8 on page 16.
2.10 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.
2.11 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:
● PLL generated clock from the STR91xF
● External oscillator U12
Clock source is selected by setting JP17. Refer to Table 2: Clock jumpers on page 12 for
configuration details.
The unplugging of hardware from t he 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.
Table 8. USB jumpers
Jumper Description
JP9
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.

2.12 Development and debugging tool support
The STR910-EVAL evaluation board supp orts connection to both In-Circuit Em ul ators (I CE)
via a 20-pin standard JTAG interface and Trace tools via a 38-pin Embedded Trace
Macrocell (ETM) interface.
To enable the ETM trace feature, some alternate circuit functions have to be disconnected
by setting the jumpers listed in Table 9. Motor control, UART1 full modem control support
and USB external 48MHz clock use STR91xF I/O pins that are required for the ETM trace
connection on CN7. These features will be restricted when ETM trace is used. The
evaluation board can not be connected to a motor control drive board on connector CN1.
To ensure the integrity of high-speed signals on the ETM trace connections, each ETM
signal should have a single point-to-point connection from STR91xF microcontroller to the
38-pin ETM connector. Stub tracks ("dead-end" extensions to the signal track) should be
eliminated. If you encounter problems when using ETM connector, you can remove the
resistors indicated in Table 9 to avoid stub and improve signal quality on the ETM
connection.

functions. Table 21 shows primary and alternate pin functions for the STR912FAW47X6 that
are used in the application board design. The table indicates the pin functions used for
STR910-EVAL peripherals in blue. If y ou choo se to imple ment th e Embedde d Trace Module
(ETM) connector for your debugging tool, you will use the alternate functions for specific
pins that are indicated in gray instead of the function indicated in blue.
