(1) emulating the detection vo ltage of the lower voltage detection circuit and power-on clear circuit in the ie-789862- ns-em1 may be affected by power supply change and noise. confirm the detection voltage with eeprom products. (2) when a program that tries to perform illegal access to eeprom is executed in the IE-789862-NS-EM1, an error message appears and the program breaks. the following shows the eeprom illegal access conditions and the error message to be displayed. table 5-1. illegal access conditions error message: unspecified illegal eeprom illegal access conditions 1 write instruction to eeprom is executed when ewe10 = 0 2 write instruction to eeprom is executed while the clock (8-bit timer 80) selected in the eeprom is stopped 3 write instruction to eeprom is executed while writing to eeprom 4 read instruction from eeprom is executed while writing to eeprom 5 instruction fetch is executed from eeprom while writing to eeprom 6 ewe10 is changed to 0 while writing to eeprom 7 ere10 is changed to 0 while writing to eeprom 8 the main clock is stopped (stop instruction is executed) while writing to eeprom 9 count clock selection of write time setting timer is changed while writing to eeprom 10 reset signal is input while writing to eeprom 11 instruction fetch from eeprom is performed when ewe10 = 1 12 writing to eeprom area 2 is performed when eewe pin is at low level 13 read instruction from eeprom is executed when ere10 = 0 14 writing to eeprom is performed when ewst = 1 (3) a 1 m ? pull-up resistor is connected to each signal related to port 4 in the IE-789862-NS-EM1. the initial value of port 4 is read as 3fh in the following environment. a) the target system is not connected b) all the p4 pins are open in the target system (4) the pocof bit (bit 2) of the power- on clear register (pocf) is set to 1 w hen the emulator is st arted up in the ie- 789862-ns-em1. therefore, clear the pocof bit (bit 2) to 0 in t he startup routine.
