Debugging Considerations

TMS320DM643

Video/Imaging Fixed-Point Digital Signal Processor

SPRS269A – FEBRUARY 2005 – REVISED APRIL 2005

It is recommended that external connections be provided to device configuration pins, including

TOUT1/LENDIAN, AEA[22:19], HD5, and TOUT0/MAC_EN. Although internal pullup/pulldown resistors

exist on these pins, providing external connectivity adds convenience to the user in debugging and

flexibility in switching operating modes.

Internal pullup/pulldown resistors also exist on the non-configuration pins on the AEA bus (AEA[18:0]). Do

not oppose the internal pullup/pulldown resistors on these non-configuration pins with external

pullup/pulldown resistors. If an external controller provides signals to these non-configuration pins, these

signals must be driven to the default state of the pins at reset, or not be driven at all.

For the internal pullup/pulldown resistors for all device pins, see the terminal functions table.
