SROM Mini-Debugger Command Set 3–13
User Commands
* Write-only registers whose values are obtained from a copy placed in PALtemp registers
1and 2 when they were written with the dc command. Therefore, changing these internal
CPU registers overwrites the saved contents of the general-purpose CPU registers 1 and 2
(also stored in PALtemp 1 and 2), affecting the output of the pr command.
Example
In the following example, output on a DS21064 CPU is displayed:
SROM> dc ! Enable machine checks and CRD interrupts
IPR> abox
D> 6
*ABOX 00000000.00000006
