SPI command and response words format

L9960 is controlled with a 16 bits command word including:



4 Address bits, 11 data bits and 1 parity bit:

The command is stored in a command register after the rising edge of NCS

The response consists of a 16 bits word which contains:



4 Address bits of the command word



12 bits as payload corresponding to the command word requested information like

diagnostic, output state, etc.

Response after reset

1st response after reset is 0000 0000 0000 0000.

Response after communication error

In case of communication error (not used commands, wrong parity bit, number of

clocks not multiples of 16) the following response is sent: 0000 0000 0000 0000.

Command Chip Select (NCS) LOW without clock is ignored.
