所算出來的時間是 10mS，你要不要再算算看及用 MPLAB SIM 設定 4MHz with 4PLL 後用Stopwatch 看中斷發生的時間。
16MHz/4 /16/250/10 = 100Hz=10mS

我想要做一個10mS的觸發訊號
我用的osc 4MHz #pragma config OSC = HSPLL T2CON = 0x8; TMR2 = 0; PR2 = 250; T2CONbits.T2CKPS0 = 1; T2CONbits.T2CKPS1 = 1; T2CONbits.T2OUTPS0 = 0; T2CONbits.T2OUTPS1 = 1; T2CONbits.T2OUTPS2 = 0; T2CONbits.T2OUTPS3 = 1; 應該會是 (4*4)osc/4/16(前除)/250(pr2)/10後除=100mhz 為什麼大於10mS呢
