BES BEN 5 Be E a a el aa a Kl i a E E Figure 3 8 CPU Bus Expansion EB and EC 3 14 intel HARDWARE OVERVIEW 3 8 LCD INTERFACE The evaluation board includes a 16 character by 1 line LCD display The display has an 8 bit interface and is designed to operate at up to 20 MHz The display includes a Hitachi 44780 LCD display controller that takes care of functions such as character interpretation and display refresh The display is write only This is because the display controller operates at 5 volts Voc A 5 volt part driving a 3 3 volt bus can damage parts operating at 3 3 volts Vcc This means that the BUSY pin of the processor cannot be monitored to determine when the processor is ready for the next command so a delay loop must be used to allow the display to finish commands Signals from the 80x186 processor can be connected directly to the LCD controller inputs regardless of Vcc because 3 3 volt and 5 volt outputs are compatible with 5 volt TTL level inputs The LCD display is mapped in I O space at 400H to 440H All command and data writes to the display are to this address Port pin 1 4 is used to control which LCD register is accessed P1 4 0 accesses the command register P1 4 1 accesses the data register 3 8 1 LCD Interface Demo The diskette provided in your kit includes a file LCD_DEMO ASM that contains source c

GO FROM code_addr GO FROM code_addr FOREVER GO FROM code_addr TILL code_addr GO FROM code_addr TILL code_addr OR code_addr GO TILL code_addr GO TILL code addrOR code addr OS HALT If a GO with breakpoint command is entered the user code bytes at the breakpoints are saved and INT3s are substituted When a breakpoint is reached the user s software stops before the instruction that caused the breakpoint and the ECM 86 software restores the original user code Note that this differs from the operation of most ICE modules which stop just after the instruction executes A problem associated with stopping before the break instruction executes is that subsequent GO commands may run into the breakpoint before any user code is executed The iECM 86 avoids this problem by skipping the setting of any breakpoints set on the instruction that the current PC points to If this happens to remove the last breakpoint set you are warned but the GO still executes with no breakpoints enabled If this happens you can use the HALT command to stop the program None of the GO commands can be executed while the user s code is already running the HALT command cannot be executed if the user s code is not running The GO commands that set breakpoints use BR 0 and possibly BR 1 Any break value already in one of these breakpoints is overwritten and destroyed by these GO commands If possible the user should reserve the first two breakpoints for use by the GO commands

RISM command The code that over rides the normal selection of command or data also clears the DATA_FLAG so that it applies only to the first character received after the SET_DATA_FLAG command 6 5 2 TRANSMIT Code 02H This command transmits the lower eight bits of the RISM_DATA register to the host right shifts the data register eight places and increments the RISM_ADDR register Sequential TRANSMIT commands are used to read the RISM_DATA register the RISM_ADDR reg ister indicates the address that corresponds to the least significant byte in the RISM_DATA register 6 5 3 READ_BYTE Code 04H This command reads the byte of memory pointed to by the RISM_ADDR register and OS places the result in the least significant byte of the RISM_DATA register 6 5 4 READ_WORD Code 05H This command reads the word of memory pointed to by the RISM_ADDR register and places the result in the least significant word of the RISM_DATA register 6 5 5 READ_DOUBLE Code 06H This command reads the double word of memory pointed to by the address register and places the result in the RISM_DATA register 6 5 6 WRITE_BYTE Code 07H This command stores the least significant byte of the RISM_DATA register in the byte of memory pointed to by the RISM_ADDR register and increments the RISM_ADDR register by one to point to the next memory byte 6 5 7 WRITE_WORD Code 08H This command stores the least significant word of the RISM_DATA register in the w
