NAME

       s51, savr, sz80 - 8051, AVR and Z80 microcontrollers simulator for SDCC.

SYNOPSIS

       s51 [options] filenames
       savr [options] filenames
       sz80 [options] filenames

WARNING

       The information in this man page is an extract from the full documentation of SDCC, and is limited to the meaning of the options.

       For complete and current documentation, refer to the ucSim simulator User Guide.

DESCRIPTION

       ucSim is a microcontroller simulator. It is extensible to support different microcontroller families.

       MCS51 family is simulated bys51.
       AVR family is simulated by savr.
       Z80 processor is simulated by sz80.

       Specified files must be names of Intel hex files. Simulator loads them in specified order into the ROM of the simulated system.

OPTIONS

       -t CPU Type  of	CPU. Recognized types are: 51, 8051, 8751, C51, 80C51, 87C51, 31, 8031, C31, 80C31, 52, 8052, 8752, C52, 80C52, 87C52, 32,
	      8032, C32, 80C32, 51R, 51RA, 51RB, 51RC, C51R, C51RA, C51RB, C51RC, 89C51R, 251, C251, DS390, DS390F. Note that recongition of a CPU
	      type  as	option does not mean that the simulator can simulate that kind of CPU. Default type is C51. DS390 supports Dallas DS80C390
	      dual-dptr operations, DS390F supports minimal flat24 mode code and dual-dptr operations.

       -X freq[k|M]
	      XTAL frequency is freq Hertz.  k or M can be used to specify frequency in kHZ or MHz. Space is not allowed between  the  number  and
	      the k or M. Default value is 11059200 Hz.

       -c file
	      Open  command  console  on  file. Command consoles are on standard input and output by default. Using this option the console can be
	      opened on any file for example on the serial interface of the computer.

       -Z portnum
	      Listen for incoming connections on port portnum. Using this option uCsim can serve multiple consoles. You can get a console by  sim-
	      ply  telnet  into  machine running uCsimto port portnumber. This option is not available on platforms which doesn't support BSD net-
	      working.

       -s file
	      Connect serial interface of the simulated microcontroller to the file. Nothing is used by default which means that characters trans-
	      mitted  by  serial  interface of the simulated microcontroller go to nowhere and it will never receive anything. If you are going to
	      communicate with serial interface interactively the best idea is to specify a teminal with -s option.

       -S in=file,out=file
	      Using this option you can specify different files for input and output streams that uCsim uses to simulate  microprocessor's  serial
	      interface.

       -p prompt
	      Using this option you can specify any string to be the prompt of command interpreter, for example:
	      $ s51 -p "s51> "

	      s51>

       -P     Prompt will be a null ('') character. This feature can be useful for programs which controlls simulator through a pipe.

       -V     Verbose mode. The simulator notifies you about some kind of internal actions for example interrupts. Messages are printed on command
	      console.

       -v     Print out version number and stop.

       -H     Print out types of known CPUs. Names printed out by this option can be used to determine CPU type using -t option.

       -h     Print out a short help about the options and stop.
