When using an on-chip emulator (E7 or E8) for

H8/36049 Group program development and debugging,

the following restrictions must be noted.

1. The NMI pin is reserved for the E7 or E8, and cannot

be used.

2. Pins P85, P86, and P87 cannot be used.

3. Area H'FFF780 to H'FFFB7F must on no account be

accessed.

4. When the E7 or E8 is used, address breaks can be

set as either available to the user or for use by the

E7 or E8. If address breaks are set as being used by

the E7 or E8, the address break control registers

must not be accessed.

5. When the E7 or E8 is used, NMI is an input/output

pin (open-drain in output mode), P85 and P87 are

input pins, and P86 is an output pin.
