When CLK_SYNC is stopped only asynchronous interrupts remain active, and any short spike
on this interrupt will wake up the device. EIC_WAKE will restart CLK_SYNC and ISR will be
updated on the first rising edge of CLK_SYNC.
The external interrupts can be used to wake up the part from sleep modes. The wakeup can be
interpreted in two ways. If the corresponding bit in IMR is one, then the execution starts at the
interrupt handler for this interrupt. If the bit in IMR is zero, then the execution starts from the next
instruction after the sleep instruction.
