(1). When receive mode is optional mode, set 1 to "receive mode change " bit (EXRR.ARP2).
------------------------------------------------------------------------------------------------------------------- Select receive mode
(2). When data should be refreshed, set 1 to "Ready to transmit" bit (RECR.ASE1).
---------------------------------------------------------------------------------------------------------------Request to refresh data
(3). EH-ETH receives the request and sends designated data to CPU. After the sending completed, EH-ETH sets 1 to
"Receiving completed" bit (C2CSR.RXC2).
------------------------------------------------------------------------------------------------------------------Receiving completed
(4). Confirm sending completed by C2CSR.RXC2=1, and cancel the "Ready to receive" bit (RDCR.ASE2). If data
should be refreshed continuously, the cancellation is not necessary.
------------------------------------------------------------------------------------------------ Cancellation of a request to refresh
(5). EH-ETH receives the request to cancel, and clear the "Receiving completion" bit (C2CSR.RXC2).
------------------------------------------------------------------------------------------------------ Clear receiving completion bit
