| * GPT : General purpose timer |
| * |
| * This timer counts up continuously while it is enabled, resetting itself |
| * to 0 when it reaches TIMER_MAX (in freerun mode) or when it |
| * reaches the value of ocr1 (in periodic mode). WE simulate this using a |
| * QEMU ptimer counting down from ocr1 and reloading from ocr1 in |
| * periodic mode, or counting from ocr1 to zero, then TIMER_MAX - ocr1. |
| * waiting_rov is set when counting from TIMER_MAX. |
| * |
| * In the real hardware, there are three comparison registers that can |
| * trigger interrupts, and compare channel 1 can be used to |
| * force-reset the timer. However, this is a `bare-bones' |
| * implementation: only what Linux 3.x uses has been implemented |
| * (free-running timer from 0 to OCR1 or TIMER_MAX) . |
