4.16 HCRC - Host CRC
Byte 35
HCRC is an 8-bit CRC code calculated according to CCITT-8
(see page 41) appended to the end of the Setups table. This
code must be sent with each serial transmission of the
Setups block.
An error in the CRC will manifest itself as an error code , and
if this occurs, factory default parameters will be automatically
loaded to provide a ‘safe’, defined recovery .
The CRC can also be replaced with a 0xD6 which will inhibit
CRC checking. Care should be taken so that the CRC is
never actually 0xD6 (if CRC checking is desired). This can
be done by altering any unused Setup parameter.
