Execution of this command will calculate a checksum for all writable, non-volatile 
parameters as currently stored in non-volatile memory. 
 
 
 
 
A device reset is initiated when the following byte sequence is sent. 
 
Read 
Byte 0 
 
 
Byte 1 
Byte 2 
Bit 0 = 1: non-volatile parameters supported 
Bit 1 = 1: CRC-32 
Bit 2..7 = 0: not used 
not used = 0x00 
not used = 0x00 
 
Write 
Byte 0 
 
 
 
Byte 1 
Byte 2 
Bit 0 = 1: use default checksum algorithm of the 
slave 
Bit 1 = 1: CRC-32 
Bit 2..7 = 0: not used 
not used = 0x00 
not used = 0x00
