Description: When the PROM Programmer is loaded, the base address parameter value is 020
16 ,
which is the CRU base address for the chassis slot most frequently used to hold the PROM
programming module interface card. After the CS subcommand is used, the software recognizes
the given CRU address until a different address is entered with the CS subcommand. There can
be no interaction with the PROM programming module unless the control software is informed
by default or by the CS subcommand of the correct CRU base address.
Error messages:
PPO I Required parameter missing.
PP02 Base address is greater than I FFE
16 •
Example:
.PP,CS,OEO
This command informs the control software that the CRU base address of the PROM pro-
gramming module is OEO
I6 •
7.5.3.4 Set Toggles (TS). The Set Toggles subcommand sets numeric parameters that inform the
control software of the actions to be taken. These numeric parameters are known as toggles. The
selected actions are not actually initiated until the PP, GO command is entered.
Syntax definition:
PP {tJ' ... } TS [{tJ' ... } [<mem diSP1 [{tJ', .. } [<prom diSP1[{tJ' ... } [<transfer>]
[{tJ' ... } <compare>]]]]
Parameters:
mem disp
prom disp
transfer
Value that specifies whether memory bit strings an'd
addresses are to be displayed. The value is 0
if no memory strings are to be displayed and
is I if memory bit strings and addresses are
to be displayed.
Value that specifies whether PROM or ROM bit strings
and addresses are to be displayed. The value
is 0 if no ROM or PROM strings are to be
displayed and is I if ROM or PROM bit
strings and addresses are to be displayed.
Value thafspecifies the data transfer option:
o
No data transfer between memory and ROM or PROM.
I PROM is to be programmed from memory datil configuration.
