Ifaka amasekhethi asebenzayo phakathi kuka-JTAG isihloko kanye ne-JTAG amadivaysi e-chain ayinconywa. Uma ukungasebenzi kahle kwesekethe, kungabangela izinkinga zokuhlela/ukuqinisekisa.

Ukusetshenziswa kwe-mixed-voltagidivayisi JTAG amaketanga ayinconywa.
- Laba ngu-JTAG amaketanga anamadivayisi asebenzisa i-VCC ehlukene voltages kanye/noma isikhombimsebenzisi voltages.
- Isixhumi esibonakalayo voltagamaleveli e-e (VIL, VIH, VOL, VOH) wamadivayisi angu-5.0V angase angahambisani ne-interface voltage amazinga amadivayisi 3.0V.

Uma i-ATMISP inenkinga yokuxhumana ne-JTAG iketango lezingxenyekazi zekhompuyutha zedivayisi, zama ukusebenzisa i-Self Calibrate noma i-Manually Calibrate ukuze wehlise amafrikhwensi we-JTAG izimpawu.
Qiniseka ukuthi i-LED kukhebuli ye-ATDH1150USB ivuliwe futhi iluhlaza ngaphambi kokuthi uhlelo luqale. Qinisekisa ukuthi ikhebuli yokulanda ye-ISP iyakwazi ukuxhumana kahle nesofthiwe ye-ATMISP.
Qiniseka ukuthi i-VCC voltagi-e isetshenziswa kukhebula ye-ATDH1150USB.
- I-VCC esetshenziswa idivayisi yokuqala ku-JTAG iketango kufanele linikezwe ikhebula le-ATDH1150USB ngephinikhodi 4 ye-10-pin JTAG unhlokweni.
- Kuma-ATF15xx CPLD ane-VCCINT ne-VCCIO ehlukene, i-VCCIO kufanele isetshenziselwe intambo ye-ATDH1150USB.
