To handle timer rollovers the test tests-mbed_hal-common_tickers_freq calls intf->set_interrupt(0). For this to work correctly the ticker implementation must fire an interrupt on every rollover event though intf->set_interrupt(0) was called only once. Whether an interrupt will fire only once or multiple times is undefined behavior which cannot be relied upon. To avoid this undefined behavior this patch continually schedules an interrupt and performs overflow detection on every read. This also removes the possibility of race conditions due to overflowCounter incrementing at the wrong time. |
