int e l 1.3 WHAT HAPPENS AFTER RESET? MCS BASIC-52 initializes the 8052AH's Special Function Registers, TMOD, TCON, and T2CON with the following values: TCON - 244 (0F4H) TMOD - 16 (10H) T2CON - 52 (34H) After Reset the console device should display the following: *MCS-51(tm) BASIC Vx.x* READY To see if everything is OK after Reset, type the following: >PRINT XTAL, TMOD, TCON, T2CON (BASIC should respond) 11059200 16 244 52 If it does, everything is working properly. If it does not make sure that the external memory, the serial port, and the oscillator are connected and working. Hardware debug begins here. In the Appendix of this manual is a QUICK REFERENCE GUIDE.
It provides a short description of all of the COMMANDS and STATEMENTS implemented in MCS BASIC-52 You might want to use this section to gain a quick understanding, of the MCS BASIC-52 software package. Those of you who are familiar with the BASIC language will notice that most of the STATEMENTS and COMMANDS used in MCS BASIC-52 are "standard," so getting started should not be a problem. - 3 -
