96.55
Checksum control
word
Bits 8…9 select which comparison(s) are made:
• Bit 8 = 1 (Approved checksum A):
96.68
Actual
checksum A
is compared to
96.71
Approved checksum
A
, and/or
• Bit 9 = 1 (Approved checksum A): if
96.69
Actual
checksum B
is compared to
96.72
Approved checksum
B
.
Bits 12…13 select approved (reference) checksum
parameter(s) into which the actual checksum(s) from
parameter(s) are copied:
• Bit 12 = 1 (Set approved checksum A): Value of
96.68
Actual checksum A
is copied into
96.71
Approved
checksum A
and/or
• Bit 13 = 1 (Set approved checksum B): Value of
