LVP通过IPE读取为OFF，但实际上在PIC16F1459中为ON

我认为这个问题已经被提到：HTTP//www. McCHIP.COM/FUMMS/M10338 70.ASPX.这里是一个详细的描述：昨天和几个月的时间，我使用IPE3.65，PICtiT3，PIC16F1459，用于LVP闪光灯；IPE3.65设置：选择：“使用低压编程模式条目”和“电源目标电路”。工具“VDD集是3.3V PIC16F1459设置：LVP=布线：RA0/RA1为PGD/PGC，它们确实工作；今天我升级到IPE 4.10，设置都是相同的，包括硬布线，但4.10以下的错误报告：”MPLAB X已经检测到设备的低电压配置位设置为OFF，但工具是S。ET到低压编程，不能编程设备。纠正这个问题：1。改变工具的编程选项使用高压编程。2。改变设备的配置位以使用低电压（LVP= ON）。用高压编程装置重新编程设备的配置位。3。将工具的编程选项改回到低电压编程，用于设备的后续编程。“我通过RC0/RC1进行闪存，改变了工具的编程选项，使用高压编程；并保持PIC的LVP= ON；Flash已成功；但在返回B时仍然会得到相同的错误。ACK在低电压下运行，如3号所述。我担心IPE4.10错误地读取PIC16F1459的配置位，因为相同的设置在IPE3.65上工作；PIC的LVP被设置，但是IPE4.10读为OFF，为什么？PIC16F1459Rev＝A6（1006）UZSLM

here is a detailed description:
yesterday and for months time,i used IPE3.65,PicKit3,PIC16F1459,for LVP flashing;
IPE3.65 setting:
selected: "use low voltage programming mode entry" and "power target circuit from tool"
VDD set is 3.3V
PIC16F1459 setting:
LVP = ON
wiring:
RA0/RA1 as PGD/PGC

and they did work;

today i upgrated to IPE 4.10,settings are all the same include hard wiring,but 4.10 report below errors:
"
MPLAB X has detected that the device’s low voltage configuration bit is set to OFF but the tool is set to low voltage programming and cannot program the device. To correct this:
1. Change the tool’s programming option to use High Voltage programming.
2. Change the device’s configuration bit to use low voltage (LVP=ON). Program the device using high voltage to reprogram the device’s configuration bit.
3. Change the tool’s programming option back to Low Voltage programming for subsequent programming of the device.
"

i did flash via RC0/RC1 with Changing the tool’s programming option to use High Voltage programming;and keep PIC's LVP = ON;flash successeded;but still get the same error when return back operating at low voltage as mentioned at above No.3.

i am afraid that IPE4.10 is wrongly reading the PIC16F1459's configuration bits,since same settings worked on IPE3.65;PIC's LVP was set ON ,but IPE4.10 read as OFF,why?
