对LVP编程感到困惑

当我注意到我的Bootloader代码编译代码有：02：0000、04、0030、Ca：01、0006、00、81、78IE，它清除了在配置4L中的LVP位。然而，我的引导加载程序成功地在没有任何高电压的情况下对其余的Flash进行编程。在这个william hill官网 中，PICtiT2（我用它来编程BooToLoad）使用高电压编程和我使用的设备的数据表（PIC18F45 K50）：“LVP位可以仅在使用标准高压编程时被设置或清除（VIHH应用于MCLR/VPP/Re3引脚）。一旦LVP已被禁用，只有标准的高电压编程是可用的，必须用于编程设备。所以我搞不清楚发生了什么事？一切都为我工作，但在上面看，好像Bootloader不应该能够编程其余的闪存…但确实如此！欢呼？库斯蒂



      以下为原文

    I was debugging something else when I noticed that my bootloader code compiled code had this:

:02 0000 04 0030 CA
:01 0006 00 81 78

ie it clears the LVP bit in CONFIG4L.

However, my bootloader code successfully programs the rest of the Flash without any high voltage.

At the same time I infer from various posts in this forum that PICKit2 (which I use to program the
bootloader) uses high voltage programming and the data sheet for the device I use (PIC18F45K50)
says:

"The LVP bit may be set or cleared only when using standard high-voltage programming (VIHH applied to the MCLR/VPP/RE3 pin). Once LVP has been disabled, only the standard high-voltage programming is available and must be used to program the device. "

So I'm confused what is going on?  

Everything works for me but looking at above it seems like the bootloader should not be able to program the rest of the flash ... but it does!?
