Table Data Processing Instructions
Section 3-17
D: First destination word
The result of the calculation is output to D if bytes have been selected.
The result of the calculation is output to D+1 and D if words have been
selected. In this case, the leftmost four digits are stored in D+1 and the right-
most four digits are stored in D.
Operand Specifications
Description
FCS(180) calculates the FCS value for C units of data beginning with the data
in R1, converts the value to ASCII code, and outputs the result to D (for bytes)
or D+1 and D (for words). The settings in C+1 determine whether the units are
words or bytes, whether the data is binary (signed or unsigned) or BCD, and
whether to start with the right or left byte of R1 if bytes are being added.
When bit 13 of C+1 has been set to 1, FCS(180) operates on bytes of data. In
this case, bit 12 determines whether the calculation starts with the rightmost
byte of R1 (bit 12 = 1) or the leftmost byte of R1 (bit 12 = 0).
