[1 shot operation]

After wake-up timer completion, move to RX_ON state. And perform CCA to check carrier. If no carrier detected, go back to

SLEEP state automatically. After wake-up timer completion, wake-up to check the carrier again. If carrier is detected, continue

RX state. Able to go back to SLEEP by setting SLEEP parameters.

○General purpose timer

ML7406 has general purpose timer. 2 channel of timer are able to function independently. Clock sources, timer setting can be

programmed independently. When timer is completed, General purpose timer 1 interrupt (INT[22] group3) or General purpose

timer 2 interrupt (INT[23] group3) will be generated.

General timer interval can be programmed as the following formula.

General purpose timer interval[s] = general purpose timer clock cycle *

Division setting ([GT_CLK_SET: B0 0x33]) *

General purpose timer interval setting ([GT1_TIMER: B0 0x34] or [GT2_TIMER: B0

0x35])

By setting GT2/1_CLK_SOURCE ([GT_SET: B0 0x32(5,1)]), clock sources for general purpose timer can be selectable from

wake-up timer clock or 2MHz.
