Write Message
I

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.
MiRICi-E3T3 handles the write message only if the number of parameter bytes is
equal to the Length field.
