• Features: -

The PTEST and PFLUSH instructions should not be executed. Execution of the PTEST
instruction causes random bus cycles to occur. Execution of the PFLUSH instruction
produces indeterminate results. Neither instruction causes the MC68EC040 to generate an
exception.
The CPUSH and CINV instructions require special consideration. A page is defined as a
4-Kbyte block of external memory. The CPUSH and CINV page instruction opcodes can be
used to push or invalidate 4-Kbyte blocks of memory. The MC68EC040 does not support
8-Kbyte pages.
The MOVEC to URP and SRP instructions are not valid and will produce indeterminate
results. Each ACU has a status register and translation control register that replace the MMU
status register and translation control register of the MC68040. The MMU status register
opcode of the MOVEC instruction can modify the ACU status register. The MC68EC040
ACU status register does not provide additional functionality to the ACU and is only provided
for compatibility with the ACU MC68EC030 status register. The ACU status register may not
be implemented in future M68EC0X0 products.
