aSC7521A
SST Interface
Multi Client Mode
Sensors operate in multi-client mode for read bit timing. Reference the SST Specification Version 1.0 for details.
SST Device Commands
GetDIB() Command (0xF7)
Read the Device Identifier Block (DIB). The read length of the command is either 8 or 16 bytes. 8 bytes is the minimum number of
bytes populated by a fixed address discoverable client.
Write Data Length:
0x01
Read Data Length:
0x08/0x10
Command Code:
0xF7
Note: Un-shaded table entries are created by the host. Shaded entries are the response bytes from the aSC7521A to the host.
