To generate periodic ping frames, the following steps must be followed:
The ping timer is a free-running counter that counts up from 0. The current value of the ping timer counter is found in TX_PING_TO_CNT. When the current value of TX_PING_TO_CNT matches the reference value TX_PING_TO_REF.TO_REF, the TX_EVT_STS.PING_TRIGGERED is set. TX_PING_TO_CNT resets to 0 and resumes counting until the next match has occurred or the ping timer is halted by software (TX_PING_CTRL.TIMER_EN is set to 0).
