The word patterns with bits [15:12] equal to $F and bits [11:9] not equal to
zero are used for coprocessor instructions. When the processor identifies a
coprocessor instruction, it runs a bus cycle referencing CPU space type $2
cessors (1-7, according to bits [11:9]). If the addressed coprocessor is not
error signal, the instruction takes an unimplemented instruction (F-line op-
code) exception. The system can emulate the functions of the coprocessor
INTERFACE DESCRIPTION for more details.
An illegal instruction exception is also taken if a breakpoint acknowledge bus
cycle (see 7.4.2 Breakpoint Acknowledge Cycle) is terminated with the as-
sertion of the bus error signal. This implies that the external circuitry did not
supply an instruction word to replace the BKPT instruction word in the in-
struction pipe.
Instructions that have word patterns with bits [15:12] equal to $F, bits [11:9]
