Softpanel
Input/Output Operations
The forms of addresses and data paterns can be found in the HP3000 Series 37 Hardware Design
Document Revision 'A'.
The options are:
RIO
ioaddr
Read I/O from address
ioaddr
WIO
ioaddr,iodata
Write I/O address
ioaddr
with data
iodata
Miscellaneous Commands
The T (Trace) comman· 1 11l0WS the user to trace the current (or specified) stack. ENV allows the user to
move back markers of the current stack and access data there as if it were at the current marker. RDX
allows the user to change the current Radix. Softpanel starts with the Radix set to octal. The ENV
command sl'ecified with no parameters will turn ENV off (q -relative addresses revert to the current
environment).
The options are:
T[
[numeric.]numeric]
Trace stack.
ENV[
numeric]
Change the environment.
RTOC tocaddr
Read TOC RAM address.
WTOC
tocaddr,tocdata
Write TOC RAM with data.
Change the current radix.
(H -
Hex; 0 - Octal)
5T
Give Softpanel status.
Memory Breakpoints
Using the SIMB breakpoint board in conjunction with the softpanel allows for breaking on absolute
memory addresses for software debugging or tracing. The breakpoint capability includes two addresses,
designated as A and B. These addresses can be set up as a range, allowing for breakpointing of a region of
memory.
A data pattern is al~o available, which allows fer breaking only on a particular pattern being written (read
data patterns are not supported) to a memory word. This data pattern can consist of ones, zeros, and don't
cares.
All memory breakpoint commands require the 51MB breakpoint board.
