Fully Integrated Single Motor Controller for Electrical Motors
The data space is organized in records (an example is shown in figure 27). Every record consists
of a 1 Byte ID number and a data item, which depending on the ID number has a certain length.
Records are read ID first and then data. Figure 28 shows the record format.

Figure 28: Record format
Once an ID is reserved it cannot be deleted. There are four categories of ID's to differentiate data
field lengths, see table 18.
ID number
Data length
0x01..0x3F
0x40..0x7F
0x80..0xBF
0xC0..0xFE

1 Byte
2 Byte
4 Byte
n Byte
ID numbers 0x01 to 0x1F and 0xC8 to 0xDF can be used for specific, application related data,
such as constants and parameters for example. ID numbers 0x00, 0xE0 to 0xFE are reserved. ID
number 0xFF is used to indicate the end of the data space.
Reading the data space starts at the highest possible address of the Shadow SRAM and continues
until ID number 0xFF is found. An ID overview is shown in table 19.
