APPENDIX A RESTRICTIONS & CPLD CODE
LISTING
The following restrictions apply to configuration level release 2.01 of the ADSP-21065L evaluation
board. For information on any ADSP-21065L silicon anomalies, see the anomaly sheet that
accompanied this product.
1. Breakpoints set in the last three instructions of a do-loop are allowed, but cause your code to run
incorrectly.
2. Breakpoints set after a delayed branch instruction and before the branch occurs causes your code
to run incorrectly.
3. Using the single stepping function
steps through a delayed branch instruction and the last
three instructions of a do-loop.
4. The host loses contact with the monitor while the user program is running if the user program
disables the UART interrupt or changes the UART interrupt vector.
5. The host loses contact with the monitor while the program is running and in an ISR when nesting
is turned off.
6. The host loses contact with the monitor while the program is running and in the timer ISR,
provided the highest priority timer vector is used.
7. The current version of the EZ-KIT monitor does not let you view hardware stack information.
8. Do not use the reset button while the debugger is open unless the debugger requests you to.This
will cause the debugger to crash.
9. The IMDW0 bit in the SYSCON register must be set to 1 to keep communication with the host.
The IMDW0 bit determines if data accesses made to block 0 are 48-bit three column accesses (1)
or 32-bit two column accesses (0). The monitor program requires three column data accesses to
memory block 0. If The IMDW0 bit is set to 0, the monitor accesses incorrect memory locations
within block 0. (See User's Manual for further discussion of IMDW0).
10. The setting of IMDW0 will have no effect on C-programming as long as RND32 is not set for 40
bit floating point precision.
11. Do not run more than one ADSP-21065L EZ-KIT Lite session in the debugger at any one time.
You may run an EZ-KIT Lite session and a simulator or ICE session at the same time or you can
open two debugger interfaces to run more than one EZ-KIT Lite session.
