Read Message
I
2
C encapsulation structure:
• Includes I
2
C Control and Write bits in the first byte.
• Next byte contains 0x80 (as the first address).
• Next byte with the First byte of the Index (MSB).
• Next byte with the Second byte of the Index (LSB).
• Next byte contains 0x01 for a read operation.
• Byte contains 0x01 for the Length.
• MiTOP-E1/T1 gets the required data byte and stores it in address 0x84.
To read the required byte, the host sends a new I
2
C message with the following
structure:
• I
2
C Control bits and Read bits in the first byte.
• Next byte contains 0x84 (the address that the parameter is read from).
• The content of address 0x84 is delivered to the host equipment.
In the event that two or more bytes are to be read, two I
2
C messages are
required to read addresses 0x84, 0x85, etc.
Write Message
I
2
C encapsulation structure:
• I
2
C Control and Write bits in the first byte.
• Next byte is 0x80 (the first address).
• Next byte contains the first byte of the Index (MSB) parameter.
• Next byte contains the second Index byte (LSB) parameter.
• Next byte is 0x00 for a write code operation.
• Byte with content of 0x01 for the Length.
From this stage the number of writes depends on the Length field.
MiTOP-E1/T1 handles the write message only if the number of parameter bytes is
equal to the Length field.
