It consists of 4 timers with identical register -// definitions offset from each other. Each timer contains a 32-bit -// counter and is capable of generating one-shot or periodic interrupts using -// a "Reload Value" register. The counter counts up and generates an interrupt -// once it rolls over from its maximum value of 0xFFFFFFFF to 0 if the -// interrupt enable bit is set. The counter always runs at a frequency of -// 10MHz. The register layout of the timer appears below: -// -// Offset Register Size -// 0x00 Timer0_Control 4 -// 0x04 Timer0_ReloadValue 4 -// 0x08 Timer0_CurrentCount 4 -// 0x0C Timer0_InterruptAcknowledge 4 -// 0x10 Timer1_Control 4 -// 0x14 Timer1_ReloadValue 4 -// 0x18 Timer1_CurrentCount 4 -// 0x1C Timer1_InterruptAcknowledge 4 -// 0x20 Timer2_Control 4 -// 0x24 Timer2_ReloadValue 4 -// 0x28 Timer2_CurrentCount 4 -// 0x2C Timer2_InterruptAcknowledge 4 -// 0x30 Timer3_Control 4 -// 0x34 Timer3_ReloadValue 4 -// 0x38 Timer3_CurrentCount 4 -// 0x3C Timer3_InterruptAcknowledge 4 -// -// Register Descriptions: -// -// TimerN_Control - This is a Read/Write register containing a bitfield of -// control values that govern the timer's operation.

Read as 0, always write 0 to maintain future -// compatibility. -// -// 2 Periodic. When set to 1, the timer will automatically reload -// itself with the value in the ReloadValue register. -// When set to 0, the timer's counter will be disabled by -// clearing the "Counter Enabled" bit when it overflows -// from 0xFFFFFFFF to 0. -// -// 1 Interrupt Enable. When set to 1, the timer will generate an -// interrupt when the counter overflows from 0xFFFFFFFF to 0. -// When set to 0, the timer will not generate an interrupt upon -// overflow. -// -// 0 Counter Enable. When set to 1, the counter is enabled and -// running. When set to 0, the counter is disable and will not -// run. -// -// TimerN_ReloadValue - This is a Read/Write register containing the value to -// reload the counter with when the timer is in Periodic mode and overflows -// from 0xFFFFFFFF to 0. Writing a value to this register also immediately -// writes the same value to the current count register. The initial value -// of this register at reset is 0. -// -// TimerN_CurrentCount - This is a Read/Write register containg the current -// value of the counter. This value can be overwritten at any time. It is -// also overwritten by a write to the ReloadValue register. The initial -// value of this register at reset is 0. -// -// TimerN_InterruptAcknowledge - This is a Read/Write register. On reads, it -// returns 1 if an interrupt is pending that has yet to be acknowledged. -// Writing a value of 0 clears the pending interrupt.

This mode is - expected to have slightly worse performance than pure periodic mode, - but is expected to generate periodic interrupts at the exact rate - specified. - - TickCount - Supplies the number of ticks from now that the timer should - assert its interrupt in.
