作為參數(shù)的地址許多命令使用ADDR作為參數(shù)。197Bug接受的語(yǔ)法是類似于單行匯編程序所接受的。所有控件尋址允許模式。還提供了“地址+偏移寄存器”模式。地址格式
地址是以十六進(jìn)制數(shù)字輸入的，地址或范圍的起始地址可以是由形式為^S、^S、^U或^U的后綴限定，其中S或S定義管理器地址空間，U或U定義用戶地址空間。默認(rèn)值，如果未指定限定符，則為Supervisor。

Address as a Parameter
Many commands use ADDR as a parameter. The syntax accepted by 197Bug is
similar to the one accepted by the one-line assembler. All control addressing
modes are allowed. An “address + offset register” mode is also provided.
Address Formats
Addresses are entered as a hexadecimal number, e.g., 20000 would correspond
to address $00020000. The address, or starting address of a range, can be
qualified by a suffix of the form ^S, ^s, ^U, or ^u, where S or s defines
Supervisor address space, and U or u defines user address space. The default,
when the qualifier is not specified, is Supervisor.
Once a qualifier has been entered, it remains valid for all addresses entered for
that command sequence, until the 197Bug is re-entered or another qualifier is
provided.Offset Registers
Eight pseudo-registers (Z0-Z7) called offset registers are used to simplify the
debugging of relocatable and position-independent modules. The listing files
in these types of programs usually start at an address (normally 0) that is not
the one at which they are loaded, so it is harder to correlate addresses in the
listing with addresses in the loaded program. The offset registers solve this
problem by taking into account this difference and forcing the display of
addresses in a relative address+offset format. Offset registers have adjustable
ranges and may even have overlapping ranges. The range for each offset
register is set by two addresses: base and top. Specifying the base and top
addresses for an offset register sets its range. In the event that an address falls
in two or more offset registers' ranges, the one that yields the least offset is
chosen.Port Numbers
Some 197Bug commands give the user the option to choose the port to be used
to input or output. Valid port numbers which may be used for these
commands are:
1. MVME197LE EIA-232-D Debug (Terminal Port 0 or 00) (PORT 1 on the
MVME197LE P2 connector). Sometimes known as the “console port”, it is
used for interactive user input/output by default.
2. MVME197LE EIA-232-D (Terminal Port 1 or 01) (PORT 2 on the
MVME197LE P2 connector). Sometimes known as the “host port”, this is
the default for downloading, uploading, concurrent mode, and
transparent modes.
Note These logical port numbers (0 and 1) are shown in the
pinouts of the MVME197 module as “SERIAL PORT 1” and
“SERIAL PORT 2”, respectively. Physically, they are all part
of connector P2.
