The Timer Register contains the current value for free-running timer.
Bits | Field | Type | Reset | Description |
---|---|---|---|---|
31:30 | eon | r | 0x0 | This is the current eon. It toggles each time the timer field is reset to 0. See Section 3.3.6.2.1.4. |
29:0 | timer | r/wtc | 0x0 |
This is the current value of the free-running counter. It increments once per clock cycle if the gasket is enabled. When the value is equal to or greater than the timeout value in the Timeout Value Register (Base Address + 0x10), it will be reset to 0 and begin incrementing again. This value only increments when the gasket is enabled. If the gasket is disabled (Enable Register (Base Address + 0x08)) and a zero is written to this field, the timer will reset to 0 and be ready to increment when the gasket is re-enabled. The eon will also be reset to 0. If the gasket is enabled, writes have no effect. See Section 3.3.6.2.1.4. |
