STEP - Set single step. SETting this flag causes the
MICMON
to single step the
CPU
n times.
If
no
valud
is
given, the
CPU
single steps once for each time the space bar
is
typed. Any other character type
causes
MICMON to exit to the command level
(MIC».
NOTE
The character typed to exit to the command level be-
comes the first character
of
the next command.
If
a
clean
start
is desired for the next command line, a
CTRLjC
must be typed to exit to the command
mode.
Example:
MIC>SE
ST
nnnn
Where
nnnn
is
the
number
of times to
single
step
the
CPU.
BREAK - Set breakpoint in console microprocessor code. SETting this flag causes the
MICMON
to
write a branch instruction to the break routine
at
the address specified. This branch instruction
is
three
bytes
long.
CAUTION: This instruction overwrites another routine's instructions.
If
the instruction
is
writ-
ten to the program area of
MICMON, a checksum error
is
printed, but this
will
not prevent the user from
executing
MICMON. The instruction replaced with the
SET
BREAK
is
not restored until a
CLEAR
BREAK or another
SET
BREAK to a new address
is
issued.
CLEAR
BREAK replaces the original three
bytes
at
the address where
SET
BREAK
was
inserted.
Example:
SET
BREAK
xxxx
Where
xxxx
is
a console microprocessor
address.
There are three special
SET
jCLEAR
functions that affect the registers
on
the Internal Disk controller
(IDC). They are SE AF,
SE
BR, and
CL
FI.
NOTE
These commands require
that
a W CS based micr-
odiagnistic
be
loaded in W CS RAM.
SE AF - Select a Fifo. Selects Fifo address register
"A"
to supply the address used when a deposit or
examine of the DBUF
is
executed.
SE
BF
- Select B Fifo. Selects Fifo address register
"B"
to supply the address used when a deposit or
examine of the DBUF
is
executed.
CL
FI - Clears the Fifo address register currently selected. This command preceeds the SE
AF
and
SE
BR commands.
SHOW - The show command causes
MICMON
to print the names of the test flags that are enabled.
SH

The flags are defined under the
SET
jCLEAR
commands.
