Description
Start Calculation
A write access to this subindex shall only
set one bit true in Bit [0...7]. If other
values are written the Abort Code
"0x06040043 Parameter is incompatible"
shall be returned.
Bit 0 = 1: Use default checksum
algorithm of the slave
Bit 1 = 1: CRC-32
Bit 2 = 1: MD5
Bit 3 = 1: SHA-1
Bit 4-6: Reserved, shall be 0
Bit 7 = 1: other algorithm
Bit 8...31: Reserved, shall be 0

Response
Byte 0: see Subindex 2
Byte 1: Unused - Shall be zero
Byte 2-n: Checksum return value. Size
varies depending on checksum type
used. The maximum length shall be 64
bytes.
