(2) Wake-up timer

By setting the following registers, after SLEEP, automatically wake-up to RX_ON state.

If SyncWord is detected before continuous operation timer-up, RX_ON will be continued to receive a packet.

After receiving RX completion interrupt(INT[8]: group2), by reading INT group2, MCU can determine read

RX data or not. In order to re-enter SLEEP state, executing SLEEP command after clearing all interrupts in INT

group2. If generating Sync error interrupt(INT[15]: group2), executing SLEEP command after clearing

RX_FIFO and INT group2.

If SyncWord cannot be detected, automatically go back to SLEEP state after continuous operation timer-up.
