78M6610+PSU Data Sheet

The following message sets the address pointer to the register (or set of registers) to read or write:

PAYLOAD

0xA3

Command

(2 Bytes)

The 78M6610+PSU replies with an acknowledge message.

Read Command

It is possible to read data from the 78M6610+PSU using the 0xE command. To read 0 to 15 bytes, the

command byte is completed with the number of bytes to read. For example, to read 3 bytes:

PAYLOAD

0xE3

Command

In order to read a larger number of bytes (up to 255), the command 0xE0 must be used. In this case, the

command 0xE0 must be followed by a byte containing the number of bytes to be read. For example to

read 31 bytes:

PAYLOAD

0xE0

Command

0x1F

(Number of Bytes to Read)

Write Command

It is possible to write data to the 78M6610+PSU using the 0xD command. To write 1 to 15 bytes, the

command byte must be completed with the number of bytes of data to write. For example to write 3 bytes:

PAYLOAD

0xD3

Command

Data

(Number of Bytes = 3)

In order to write a larger number of bytes (up to 255), the command 0xD0 must be used. In this case, the

number of data bytes to follow is determined by the Byte Count. For example to write 31 bytes:

PAYLOAD

0xD0

Command

Data

(Number of Bytes = Byte Count – 4)

After each read or write operation, the internal address pointer is incremented to point to the address that

followed the target of the previous read or write operation.
