Preface
The H8/3694 Series is a single-chip microcomputer made up of the high-speed H8/300H CPU as
its core, and the peripheral functions required to configure a system. The H8/300H CPU has an
instruction set that is compatible with the H8/300 CPU.
Target Users: This manual was written for users who will be using the H8/3694 Series in the
design of application systems. Target users are expected to understand the
fundamentals of electrical circuits, logical circuits, and microcomputers.
Objective: This manual was written to explain the hardware functions and electrical
characteristics of the H8/3694 Series to the target users.
Refer to the H8/300H Series Programming Manual for a detailed description of the
instruction set.
Notes on reading this manual:
•
In order to understand the overall functions of the chip
Read the manual according to the contents. This manual can be roughly categorized into parts
on the CPU, system control functions, peripheral functions and electrical characteristics.
•
In order to understand the details of the CPU's functions
Read the H8/300H Series Programming Manual.
•
In order to understand the details of a register when its name is known
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 19,
Internal I/O Registers.
Example: Bit order: The MSB is on the left and the LSB is on the right.

Notes:
When using on-chip emulator (E10T) for H8/3694 program development and debugging, the
following restrictions must be noted.
1. The
NMI
pin is reserved for the E10T, and cannot be used.
2. Pins P85, P86, and P87 cannot be used. (In order to use these pins, additional hardware
must be provided on the user board.)
3. Area H’7000 to H’7FFF is used by the E10T, and is not available to the user.
4. Area H’F780 to H’FB7F must on no account be accessed.
