- Lub system pawg thawj coj saib xyuas lub xeev ua haujlwm tsis tau txhais; thiab yog li ntawd, kev ua haujlwm tsis raug yuav tshwm sim.

Inserting active circuits ntawm JTAG header thiab JTAG cov khoom siv hauv cov saw hlau tsis pom zoo. Yog hais tias lub active circuit malfunctions, nws yuav ua rau programming / xyuas cov teeb meem.
Kev siv cov mix-voltage device JTAG chains tsis pom zoo.
- Cov no yog JTAG chains nrog cov khoom siv sib txawv VCC voltages and/or interface voltages.
- Interface voltage theem (VIL, VIH, VOL, VOH) rau 5.0V li tej zaum yuav tsis tau tshaj interface voltage theem rau 3.0V li.
Yog tias ATMISP muaj teeb meem sib txuas lus nrog JTAG ntaus ntawv kho vajtse, sim khiav Tus Kheej Calibrate lossis Manually Calibrate kom txo qis zaus ntawm JTAG teeb liab.
Xyuas kom tseeb tias lub LED ntawm ATDH1150USB cable yog qhib thiab nws yog ntsuab ua ntej lub programming pib. Xyuas kom ISP download cable muaj peev xwm sib txuas lus nrog ATMISP software.

Xyuas kom tseeb tias VCC voltage yog siv rau ATDH1150USB cable.
- VCC siv los ntawm thawj lub cuab yeej hauv JTAG saw yuav tsum muab nkag rau ATDH1150USB cable ntawm tus pin 4 ntawm 10-pin JTAG taub hau.
- Rau ATF15xx CPLDs nrog cais VCCINT thiab VCCIO, VCCIO yuav tsum siv rau ATDH1150USB cable.
