Instruction characteristics
The Primary Instructions Table 6.3 gives the basic function code. Where the operand is less than
16, a single byte encodes the complete instruction. If the operand is greater than 15, one prefix
instruction (pfix) is required for each additional four bits of the operand. If the operand is negative
the first prefix instruction will be nfix Examples of pfixand nfixcoding are given in Table 6.1.
Any instruction which is not in the instruction set tables is an invalid instruction and is flagged
illegal, returning an error code to the trap handler, if loaded and enabled.
The
Notes
column of the tables indicates the descheduling and error features of an instruction as
described in Table 6.2
