Chapter 4 Q & A
1. How to check a failed buffer?
There are two ways to know the buffer is failed:
(1) The fail message is displayed on the output window whenever the “load” command is
executed.
(2) The LED on the top of the hardware keeps blinking fast (5 times per second ) all the
time no matter users put power-on, or just push the red button.
2. What is “Frequency Mode”?
If the application system is below 200 kHz, the low frequency must be selected. Otherwise,
the high frequency is selected.
3. What is “Code Protected”?
Once the protection function is enabled, the contents of the OTP ROM would not be read
any more. The values displayed on the screen do not mean anything
4. What is status of LED?
(1) On under programming. Wait for LED turns off.
(2) Off: programming OK.
(3) Slow blinking (1.5 cycles per second): programming failed.
