Table 2.33 Correspondence between DSP Instruction Operands and Registers
Register

When writing parallel instructions, write the B field instructions first, then write the A field
instructions:
Text in brackets ([]) can be omitted. The no operation instructions NOPX and NOPY can be
omitted. Semicolons (;) are used to demarcate instruction lines, but can be omitted. If semicolons
are used, the space after the semicolon can be used for comments.
The individual status codes (DC, N, Z, V, GT) of the DSR register are always updated by
unconditional ALU operation instructions and shift operation instructions. Conditional instructions
do not update the status codes, even if the conditions have been met. Multiplication instructions
also do not update the status codes. DC bit definitions are determined by the specifications of the
CS bits in the DSR register.
Table 2.34 lists the DSP operation instructions by classification.
