A cyclic communications interrupt (INT1) is input to the host controller every transmission cycle, so send and
receive processing is performed during this interrupt between communications cycles. For all other interrupts,
the send and receive processing must be skipped and the cyclic communications interrupt processing must be
ended. Do not wake up the send and receive processing every time entering into interrupt handler.
