我提供另一解決方法；你可以找一顆切換式電源IC，我有用過NATIONAL的IC，NATIONAL可申請免費樣品。參考一下吧。

謝謝各位先進！
後輩有使用"PAGESEL SUB_XXX"(in page 1 from page 0)，可以讓程式正確GOTO到你想去的PAGE，但是若你下面的程式要再GOTO(in PAGE 1 )的話，還要再一次把PAGE調回來，跟大家分享一下，謝謝大家。

謝謝先進！
我有去mplab HELP看，而且有找到下列資料:

Creating a Synchronous Stimulus File

To create a Synchronous Stimulus file:

1. Click the File Stimulus tab of the Simulator Stimulus dialog (Debugger>Stimulus).
2. Click Add under "Input Files". Enter stim1 for "File Name" and click OK in the Open dialog. The file name should appear in the file list box, i.e., C:\SimProj\
stim1.ssti.
3. Click on the file name to select the file. Click Edit under "Input Files". This will disable some "Input Files" buttons and enable the "Edit Controls" buttons.
4. Click Add Row under "Edit Controls". A row will appear for entering data.
5. Set up the row for file injection into a register as follows:
Select "PC" under "Trigger On".
Note: You must use PC with register stimulus.

Enter 0x1a under "Trig Value".
Select TRISB under "Pin/Register".
Note: You cannot inject file values into port registers, e.g., PORTB. Use pin values (explained next.) Also, you cannot inject file values into the W register.

6. Select "File" under "Value". This will open a dialog to select a register stimulus file. Select reg1.rsti and click Open to enter this file under "Value".

但是在第6步驟時，Select reg1rsti，我都找不到 .rsti類型的檔案，而後輩是使用MPLAB v6.6版。請問先進，謝謝！

請問先進:
Crossing page boundary -- ensure page bits are set是使用GOTO與CALL指令時，所產生的嗎？
我有試過改變PCLTH<4，3>的值，但是在PAGE 1 不行
，如下:
BANKSEL PCLATH
BCF PCLATH,4
BCF PCLATH,3
CALL ADSTART
請先進指點。
謝謝ㄌ

請問先進:
