Write transaction
A write transaction (see
nSS pin. The other bits are then sent on the MOSI pin with this order:
1.
2.
3.
4.
The data to be written (MSB first D15…D0) are then read from MOSI pin. The length of data
field can be 16 or 20 bits, but only the first 16-bit are accepted as valid data. Data is latched
on rising edge of the nSS line.
The SPI input and output timing definitions are shown in the

A6
7-bit representing the address of the register that must be written (MSB first [A6…A0]);
2-bit that must be “01” for a read transaction;
2-bit representing L6460 IC address;
1-bit reserved for future use that must be set at “0”.
