建議先把這篇有關 PIC24 oscillation user's manual 看完，並了解如何對 OSCCON 暫存器來做解鎖的動作。

請教各位先進, 如何在進入用軟體切換 24FJ256 的執行速度, 硬體上現有的兩個 Crystal 32768Hz & 32MHz 的運作都是正常的, 在 C30 的安裝目錄下 C:\Program Files\Microchip\MPLAB C30\src\peripheral_24F\src\pmc\PwrMgnt 找到一個 source code "PwrMgnt_OscSel.c" 但是實際使用時, 一直都傳回 "FALSE", 看起來像是 OSCCON bit 7 CLKLOCK 位元沒有解除, 造成的, 請問要如何解決這個問題?
