// Start Timer:

// Stop Timer:
//

// Reload Timer With period Value:
//
#define ReloadCpuTimer0() CpuTimer0Regs.TCR.bit.TRB = 1

//
// Read 32-Bit Timer Value:
//
#define ReadCpuTimer0Counter() CpuTimer0Regs.TIM.all

//
// Read 32-Bit Period Value:
//
#define ReadCpuTimer0Period() CpuTimer0Regs.PRD.all

//
// Start Timer:
//
#define StartCpuTimer1()   CpuTimer1Regs.TCR.bit.TSS = 0
#define StartCpuTimer2()   CpuTimer2Regs.TCR.bit.TSS = 0

//
// Stop Timer:
//
