Notes:
When using the on-chip emulator (E7, E8) for H8/3687
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.
3. Area H'D000 to H'DFFF is used by the E7 or E8, and is not
available to the user.
5. 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.
6. 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.
7. Use channel 1 of the SCI3 (P21/RXD, P22/TXD) in on-
board programming mode by boot mode.
