A host-side transceiver device that receives, from a host device , an access request signal for requesting access to a remote device from the host device and sends the access request signal to a remote-side transceiver device that performs communication with the remote device , the host-side transceiver device comprising: a first communication unit that performs communication based on an in-device data bus communication scheme with the host device and receives the access request signal sent from the host device , wherein the in-device data bus communication scheme is an inter-integrated circuit, I 2 C, communication scheme or a serial peripheral interface, SPI, communication scheme; and a second communication unit that performs communication based on a communication scheme different from the in-device data bus communication scheme with the remote-side transceiver device , and sends the access request signal received by the first communication unit to the remote-side transceiver device , wherein the first communication unit sends a reception notification signal for notifying that the first communication unit has received the access request signal sent from the host device , to the host device , before the access request signal sent from the second communication unit reaches the remote device , wherein the access request signal is a read request signal requesting to read data from the remote device , and wherein when the second communication unit has received, from the remote-side transceiver device , an end notification signal for notifying that the access to the remote device based on the access request signal sent from the second communication unit has ended, the first communication unit notifies the host device that the end notification signal has been received. a first communication unit that performs communication based on an in-device data bus communication scheme with the host device and receives the access request signal sent from the host device , wherein the in-device data bus communication scheme is an inter-integrated circuit, I 2 C, communication scheme or a serial peripheral interface, SPI, communication scheme; and a second communication unit that performs communication based on a communication scheme different from the in-device data bus communication scheme with the remote-side transceiver device , and sends the access request signal received by the first communication unit to the remote-side transceiver device , wherein the first communication unit sends a reception notification signal for notifying that the first communication unit has received the access request signal sent from the host device , to the host device , before the access request signal sent from the second communication unit reaches the remote device , wherein the access request signal is a read request signal requesting to read data from the remote device , and wherein when the second communication unit has received, from the remote-side transceiver device , an end notification signal for notifying that the access to the remote device based on the access request signal sent from the second communication unit has ended, the first communication unit notifies the host device that the end notification signal has been received. <EOS>
