Libra 你好

我使用未編輯過的MCU可以正常連接可以讀取 Configuration bits
我嘗試做修改 sut cksel 燒入後
再度讀取 Configuration bits 就無法讀取
斷電重新再讀取一樣 Connection Failed.
這顆MCU就無法再連線
要是 Configuration bits 設置錯誤 要如何可以重新回復原廠設定

Libra 你好
ATtiny2313A(AVR-ISP) -> PICkit 5
-------------------------------------------------------
18 (PB6, MISO) -> PGD (Data) 4
17 (PB5, MOSI) -> TTDI (Test Data In) 7
19 (PB7, SCK) -> PGC (Clock) 5
1 (RESET) -> MCLR (Master Clear) 1
20 (VCC) -> VDD (Power) 2
10 (GND) -> GND (Ground) 3

這樣連接後依然產生下列錯誤..

Connecting to MPLAB PICkit 5

在MPLAB IDE 6.15 設置是否要改 Speed(MHz)數值要改多少
options for pickit5-->communications
interface ISP
Speed(MHz) 0.125

硬體方面有需要做提升電阻之類的設置嗎

您好
請問高人們
我使用MPLAB IDE 6.15 連接pickit5 想對ATtiny2313A做開發
引腳要如何對接
