Intel mcs-48 manual ICE·49, Isis·Ii

ICE·49

Cable Card

The cable card is included for cable driving. It transmits address and data bus information to the user system through a 40·pin connector which plugs into the user system in the socket designed for the MCS·48device.

Software

CommandOperation

Display Prints contents of memory, MCS·48 device registers, 1/0 ports, flags, pins, real·time trace data, symbol table, or other diagnostic data on list device.

Change Alters contents of memory, register, output port, or flag. Sets or alters break· pOints and display registers.

The ICE·49 software driver Is a RAM·based program which provides the user with an easy to use command language (see Table 1, Table 2, and Table 3) for defining breakpoints, initiating real·timeemulation or single step operation, and interrogating and altering user system status recorded during emulation. The ICE·49command language contains a broad range of modifiers to provide the user with maximum flexibility in defining the opera· tion to be performed. The ICE·49 software driver is available on diskette and operates in 32K of Intellec RAM memory.

Map	Defines memory status.
Base	Establishes mode of display for output
	data.
Suffix	Establishes mode of display input data.
Table 2. ICE·49Interrogation Commands
Command	Operation
Load	Fetches user symbol table and object
	code from input device.

Command	Operation
Enable	Activates breakpOint and display regis·
	ters for use with go and step com·
	mands.
Go	Initiates real·timeemulation and allows
	user to specify breakpoints and data
	retrieval.
Step	Initiates emulation in single instruction
	Increments. Each step is followed by
	register dump. User may optionally
	tailor other diagnostic activity to his
	needs.
Interrupt	Emulates user system interrupt.

Table 1. ICE·49Emulation Commands

Save	Sends user symbol table and object
	code to output device.
Define	Enters symbol name and value to user
	symbol table.
Move	Moves block of memory data to another
	area of memory.
list	Defines list device.
Exit	Returns program control to ISIS·II.

Evaluate Converts expression to equivalent values in binary, octal, decimal, and

	hex.
Remove	Deletes symbols from symbol table.
Reset	Reinltiallzes ICE·49 hardware.
