无法得到Time1计数

我想得到比time0或Time1单独的时间更长的时间。我认为我可以通过使用Time0来控制Time1门，通过设置1GCONTITS。T1GSS= 0B01；我已经尝试了很多不同的设置，但似乎无法得到Time1计数与大门。有人能帮忙吗？？？？谢谢！

    I wanted to get a longer time than what timer0 or timer1 can do alone.  I thought that I could control the timer1 gate using timer0 by setting T1GCONbits.T1GSS = 0b01;.  I have tried many different settings but can't seem to get Timer1 counting with the gate on.  Could someone please help?!?!

Thanks,

//config timer 1
T1CONbits.T1CKPS = 0b00;//timer 1 prescale
T1CONbits.TMR1CS = 0b00;//timer 1 clock source instruction clock(Fosc/4)
OSCCONbits.IRCF = 0b0000;//31KHz, clock determined in configeration word 1
T1CONbits.TMR1ON = 1;//turn on timer1
T1GCONbits.TMR1GE = 1;//gate control
T1GCONbits.T1GSS = 0b01;//gate source selection
T1GCONbits.T1GTM = 1;//gate is in toggle mode, clear puts it into single pulse mode
T1GCONbits.T1GSPM = 0;//single pulse mode
T1GCONbits.T1GPOL = 0;//gate polarity
T1CONbits.nT1SYNC = 1;

//config timer 0
OPTION_REGbits.TMR0CS = 0;//timer 0 clock source internal instruction clock (Fosc/4))
OPTION_REGbits.PSA = 0;//Prescaler assigned to timer 0
OPTION_REGbits.PS = 0b000;//prescale 1:256 = 111

//Setup interrupts
INTCONbits.GIE = 1;//enable all interrupts
INTCONbits.PEIE = 1;//enable Peripheral interrupts (timer1, AD, Rx, Tx, LCD)
INTCONbits.TMR0IE = 1;//timer0 interrupt 1 = enabled
PIE1bits.TMR1IE = 1;//timer 1 interrupt

void interrupt Interrupts(void){
if(INTCONbits.TMR0IF == 1 && INTCONbits.TMR0IE == 1){
//Timer 0 overflow
INTCONbits.TMR0IF = 0;//clear the interrupt flag
}
if(PIR1bits.TMR1IF == 1){
//Timer 1 overflow
PIR1bits.TMR1IF = 0;//reset the flag
}
}
