Host-side transceiver device and transceiver system

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;
• 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 to the remote device based on the access request signal sent from the second communication unit ends;
• and
• wherein when the access request signal is a write request signal to the remote device, the write request signal requests writing data from the remote device.
