P0927AJ通讯模块，FOXBORO英文使用说明
语法变量下面显示的语法变量在以下页面中的命令说明。此外，其他可以使用语法变量，并在特定的它们出现的命令描述。分隔符；逗号或空格。exp表达式（在下一节中详细描述）。
地址（在下一节中详细描述）。计数；语法与exp相同。范围可以指定的内存地址范围按地址del addr或按地址：count。文本最多255个字符的ASCII字符串，
P0927AJ通讯模块在每个端点由单引号（'）表达式作为参数表达式可以是一个或多个由算术运算符：加号（+），减号（-），乘以（*），除以
按（/）、逻辑与（&）、左移（<<）或右移（>>）。数值可以用十六进制、十进制、，八进制或二进制，直接在其前面加上适当的基本标识符。如果未指定基本标识符，则假设数值
十六进制。数值也可以表示为最多为的字符串文字四个字符。字符串文字必须以开头和结尾
单引号（'）。数值被解释为字符ASCII值的串联。这个值是右对齐，与任何其他数值一样。表达式的求值总是从左到右，除非括号用于对表达式的一部分进行分组。没有
运算符优先级。括号内的子表达式为首先评估。计算嵌套的插入子表达式由内而外。有效表达式示例：作为参数的地址许多命令使用addr作为参数。接受的语法
187Bug与M88000单线所接受的类似汇编程序。允许所有控制寻址模式。“地址”+还提供了“偏移寄存器”模式
Syntactic Variables
The syntactic variables shown below are encountered in the
command descriptions on the following pages. In addition, other
syntactic variables may be used and are defined in the particular
command description in which they occur.Delimiter; either a comma or a space.
exp Expression (described in detail in a following section).
addr Address (described in detail in a following section).
count Count; the syntax is the same as for exp.
range A range of memory addresses which may be specified
either by addr del addr or by addr: count.
text An ASCII string of up to 255 characters, delimited at
each end by the single quote mark (')Expression as a Parameter
An expression can be one or more numeric values separated by the
arithmetic operators: plus (+), minus (-), multiplied by (*), divided
by (/), logical AND (&), shift left (<<), or shift right (>>).
Numeric values may be expressed in either hexadecimal, decimal,
octal, or binary by immediately preceding them with the proper
base identifier.If no base identifier is specified, then the numeric value is assumed
to be hexadecimal.
A numeric value may also be expressed as a string literal of up to
four characters. The string literal must begin and end with the
single quote mark ('). The numeric value is interpreted as the
concatenation of the ASCII values of the characters. This value is
right-justified, as any other numeric value would be.Evaluation of an expression is always from left to right unless
parentheses are used to group part of the expression. There is no
operator precedence. Subexpressions within parentheses are
evaluated first. Nested parenthetical subexpressions are evaluated
from the inside out.
Valid expression examples:
Address as a Parameter
Many commands use addr as a parameter. The syntax accepted by
187Bug is similar to the one accepted by the M88000 one-line
assembler. All control addressing modes are allowed. An “address
+ offset register” mode is also provided.
