10.7. Supply level detection
10.8. EEPROM
10.9. Sys.Clk.Adj.
It is possible to simulate changes in the supply level from 0V to 5V with the use of
the scroll bar. The minimum precision is 0.01V, although steps of 0.1V can be
obtained using the page-up and page down function keys. It should be noted that
reducing the supply voltage to 0V would not stop the software simulation of the
microcontroller.
The contents of the internal EEPROM of the EM6640 are shown in the EEPROM
section. The data is in hexadecimal format and is read only.
Shows the 6-bit configuration (OscAdj [0] to OscAdj [5]) contained in register
OPTOscAdj and OPTPaRST. These bits are used to « trim » the chip’s RC
oscillator. The simulated controller only displays the status of this trimming, but, as it
is not « real time », its speed is not affected.
