50. ult If the push button switches are not being used as an interrupt or other it is best to remove the shunt to the DSC so that the 0 1 uF capacitor is not loading down the DSC pins 2 3 10 RESET The GPIOD4 RESET_B pin of the DSC is connected to the motor control connector and the Tower connector but also to a push button SW3 and through buffers to the OSBDM chip It is pulled to P3_3V by a 10K ohm resistor It may be pulled low by the push button or by Q1 in response to a high output from the OSBDM chip pin 1 on the TRESET_OUT net The state of the GPIOD4 RESET_B signal is provided to the OSBDM chip through a voltage translator U504B This buffer is powered by the P3_3V 5V power rail so that its input will remain high impedance when there is no USB cable connected The buffered RESET signal is provided to pin 33 of the OSBDM chip and is used by the OSBDM program in that chip 2 3 11 JTAG Header and OSBDM Disconnect Header The TWR 56F8257 board includes an OSBDM circuit as a debug interface to the MC56F8257 DSC for normal purposes If the user desires to use a different debugger header J14 provides a connection point for an external JTAG based debugger If an external debugger is connected to the JTAG header the shunts at J21 pins 1 to 2 3 to 4 5 to 6 and 7 to 8 which connect the OSBDM circuit to the JTAG signals should be removed The TWR 56F8257 board provides a 2 2K ohm pull up resistor to 3 3V on the TMS line If an external JTAG debu
