Instruction Format Summary
8.1.5 Destination Register Field
This field is common to all arithmetic instructions. It specifies the FPDR that that will be the
destination. The results are always stored in this register.
8.1.6 Conditional Predicate Field
This field is common to all conditional instructions and specifies the conditional test that is
to be evaluated. Table 8-1 shows the binary encodings for the conditional tests.
8.1.7 Shift and Rotate Instructions
The following paragraphs define the fields used with the shift and rotate instructions.
8.1.7.1 Count Register Field. If i/r = 0, this field contains the rotate (shift) count of 1 – 8 (a
zero specifies 8). If i/r = 1, this field specifies a data register that contains the rotate (shift)
count. The following shift and rotate fields are encoded as follows:
8.1.7.2 Register Field. This field specifies a data register to be rotated (shifted).
8-2
