Symbol Address Description
INAddrMSB 0x7F4 MSB Address of the data to be sent to host PC when interrupt is generated into
the HelloDevice from user device
INAddrLSB 0x7F5 LSB Address of the data to be sent to host PC when interrupt is generated into
the HelloDevice from user device
INLenMSB 0x7F6 MSB length of the data to be sent to host PC when interrupt is generated into the
HelloDevice from user device
INLenLSB 0x7F7 LSB length of the data to be sent to host PC when interrupt is generated into the
HelloDevice from user device
OUTAddrMSB 0x7F8 MSB Address of the data to be read by user device when interrupt is generated
into user device
OUTAddrLSB 0x7F9 LSB Address of the data to be read by user device when interrupt is generated
into user device
OUTLenMSB 0x7FA MSB length of the data to be read by user device when interrupt is generated
into user device
OUTLenLSB 0x7FB LSB length of the data to be read by user device when interrupt is generated into
user device
INTR_R 0x7FE Used that HelloDevice generates interrupt into user device.
If the HelloDevice sets this register value as 0xAA, interrupt will be generated
into user device.
INTR_L 0x7FF Used that user device generates interrupt into the HelloDevice.
If user device sets this register value as 0xAA, interrupt will be generated into
the HelloDevice.

6.2 Communication Protocol
To read and write the HelloDevice Dual-Port RAM remotely on the Internet, the Internet socket interface
program should be implemented on the your PC to communicate with the HelloDevice. This socket interface is
usually implemented in the form of a socket program written in C or Java applet working on the web.
The Internet socket interface should be implemented to allow the TCP/IP protocol to communicate with the
HelloDevice, and it should send Read/Write command to the TCP port 6001 and current IP address of the
HelloDevice. The HelloDevice will interpret this command to read and write Dual-Port RAM of the HelloDevice.
The communication command and corresponding response between socket interface and the HelloDevice are
summarized in Table 6.2.
