execution until all previous operations, including all pending write operations, are complete. If any
previous write terminates with an access error, it is guaranteed to be reported on the NOP instruction.
2.3.4.2
Any attempted execution transferring control to an odd instruction address (if bit 0 of the target address is
set) results in an address error exception.
Any attempted use of a word-sized index register (Xn.w) or a scale factor of eight on an indexed effective
addressing mode generates an address error, as does an attempted execution of a full-format indexed
addressing mode, which is defined by bit 8 of extension word 1 being set.
If an address error occurs on a JSR instruction, the Version 2 ColdFire processor calculates the target
address then the return address is pushed onto the stack. If an address error occurs on an RTS instruction,
the Version 2 ColdFire processor overwrites the faulting return PC with the address error stack frame.
2.3.4.3
The ColdFire variable-length instruction set architecture supports three instruction sizes: 16, 32, or 48 bits.
The first instruction word is known as the operation word (or opword), while the optional words are known
as extension word 1 and extension word 2. The opword is further subdivided into three sections: the upper
four bits segment the entire ISA into 16 instruction lines, the next 6 bits define the operation mode
(opmode), and the low-order 6 bits define the effective address. See
