參考這份官方文件看看:Header Board Specification，裡面有介紹header的電路。
Microchip有些mcu確實沒有debuger的電路在裡面，所以沒有辦法用icd2去做debug。當你用header做debug時，是不需要16F628A，直接用header mcu代替它。
這問題我也卡過一次!!

Thanks.
再請問一下,轉接座(AC162053)本身就可模擬PIC16F628A的
功能嗎(不需在接16F628A)?
還是ICD2接轉接座(AC162053)後,在接至16F628A的Chip呢?
PIC16F628A內部是否無Debug電路,所以ICD2 Debug時須外接轉接座(AC162053)?

PIC16F628A 的轉接座編號 : AC162053

如果是直接拿PIC16F628A是無法使用ICD2 Debug的,需要購買轉接的Header才行哦~

請問 PIC16F628A在compiler完後,用ICD2可以燒錄並執行,但是換成debug mode就會出現Invalid target device id及Unable to enter debug mode到底問題出在哪?
Confg. bits : OSC(HS),LVP(Disable),Code Protect(Disable),
WDT(Disable)等我都檢查過了,且用16f628ai.lkr檔.是否有哪裡
沒設定好呢?
