PICkit 3 FOSC_INTOSCIO T1OSCEN只编程一次下一次失败

嗨，程序后，一个空白的PIC16F68A/I/P与皮卡3（原来的串行Bur1437×XXXX）下一次我想重新编程设备，但我得到下一个消息：目标设备ID（0x0）是一个无效的设备ID。请检查您的连接到目标设备。设备擦除…编程…埃默里区域（s）将被编程：程序存储器：起始地址＝0x0，结束地址＝0x4ACCONtiON COMPLE程序内存地址：0预期值：2834接收值：编程装置失败，它具有RA7和RA6作为I/O使能的内部振荡器使能。nable为32.768 kHz晶体，当我将配置位更改为水晶（μfSCORXXT）并编程一个新的空白设备，然后我重新编程，它按预期工作，并且可以按照我想要的时间重新编程，但是当我换到内部振荡器时，它又失败了产品版本：MPLAB X IDE V3.55 JAV。A:1.8O.991；Java热点（TM）64位服务器VM 25.91-B14RunTime:Java（TM）SE运行时环境1.80y91-B14系统：运行在AMD64上的Windows 10版本10；CP1252；EnUUS（MPLAB）用户目录：C:\xxxxxxxxAppDATaROMAMMPLABIDIDDEVV3.55高速缓存目录：C:XXXXX xxxxAppDATABLOCAMPLABIDIDCache DEVV3.55 var

    Hi,

After program a blank PIC16F648A-I/P with PICkit 3 (original Serial# BUR1437XXXXX) next time I want to re-program the device but I get the next message:

Target Device ID (0x0) is an Invalid Device ID. Please check your connections to the Target Device.

Device Erased...

Programming...

The following memory area(s) will be programmed:
program memory: start address = 0x0, end address = 0x4ac
configuration memory
program memory
Address: 0 Expected Value: 2834 Received Value: 0
Failed to program device

it has the internal oscillator enable with RA7 and RA6 as I/O enable (_FOSC_INTOSCIO) and the T1OSCEN enable for a 32.768 kHz crystal

When I change the configuration bit to Crystal (_FOSC_XT) and program a new blank device, then I re-program again it works as expected and can re-program as many time as I want, but when I change to internal oscillator it fail again
