Now consider the low power modes of the device. Low power modes are available on both the M3 Master subsystem and the C28x Control subsystem. The M3 low power modes include a normal mode, a sleep now mode, a sleep on exit and a deep sleep mode. The C2000 low power modes include normal, idle and standby. Exit and entry from low power modes is controlled by separate logics on both of the subsystems. Therefore, the user can have one subsystem in a low power mode while the other subsystem is running. The one exception to this is the deep sleep mode. Before the M3 enters deep sleep, the C28x should be in standby. Also deep sleep wake up is from the M3 or the master side. Refer to the data manual for more information on current consumption in different low power modes.
