A tasks的周期问题

// -------------------------------- FRAMEWORK --------------------------------------

// Alpha states
void A0(void); //state A0
void B0(void); //state B0
void C0(void); //state C0
// A branch states
void A1(void); //state A1
void A2(void); //state A2
void A3(void); //state A3
void A4(void); //state A4
// B branch states
void B1(void); //state B1
void B2(void); //state B2
void B3(void); //state B3
void B4(void); //state B4
// C branch states
void C1(void); //state C1
void C2(void); //state C2
void C3(void); //state C3
void C4(void); //state C4
// Variable declarations
void (*Alpha_State_Ptr)(void); // Base States pointer
void (*A_Task_Ptr)(void);  // State pointer A branch
void (*B_Task_Ptr)(void);  // State pointer B branch
void (*C_Task_Ptr)(void);  // State pointer C branch
CpuTimer0Regs.PRD.all =  mSec5;  // A tasks
CpuTimer1Regs.PRD.all =  mSec10; // B tasks
CpuTimer2Regs.PRD.all =  mSec100; // C tasks
// Tasks State-machine init
Alpha_State_Ptr = &A0;
A_Task_Ptr = &A1;
B_Task_Ptr = &B1;
C_Task_Ptr = &C1;
void A1(void) // SCI-GUI
//--------------------------------------------------------
[
//SerialHostComms();  // Serialport controls LED2 (GPIO-31)
       // Will not blink until GUI is connected
      
  test_time++;
  
//the next time CpuTimer0 'counter' reaches Period value go to A2
A_Task_Ptr = &A2;
//-------------------

A tasks的周期是5ms,B tasks 的周期是10ms,C tasks的周期是100ms,
我把测试变量 test_time++放在void A1()函数中，为什么不计数？？
