Chapter 5 Notes on Use of EASE1000
(7) About the status window of execution time
The accuracy of Timer displayed in the status window of DTU8 is 100us units. The maximum time which can be
measured is 119 hours. If the maximum time is exceeded, a count will be continued from 0us.
The value of Timer is measured by the timer of EASE1000. Therefore, it differs from the execution time of LSI.
When a measurement period is short, an error of measurement becomes large.
Timer value = Execution time of LSI ± 0.2 % + 300us
5.2 About the 3.3VOUT pin
The specification of the 3.3VOUT pin is 3.3V/100mA.
When using the 3.3VOUT pin with the target system, do not exceed the range of specification.
Using exceeding specification, may damage the target system or EASE1000.
5.3 About Usage Environment
EASE1000 may be affected by the external environment of the host PC, USB cable, EASE1000 interface cable, and
the target system. Please check the operation in the specific customer environment before use.
5.4 About Flash Writing
Confirm before using EASE1000 as a flash writer that the target LSI power supply voltage (V
DD
) is within the range
of the flash memory operating condition.
Also, confirm that the application program operates normally after writing.
5.5 About Cables
Be sure to use the USB cable and EASE1000 interface cable supplied as EASE1000 accessories. The operation is not
guaranteed if a cable other than the EASE1000 accessories is used.
Note
Be sure to use the cables attached to EASE1000.
Using different cables may damage EASE1000 or the target system, or cause an electric shock
or fire.
