Section 2 Specification of the E10A Emulator’s Software

2.1 Differences between the H8S/2378F, H8S/2377F, H8S/2367F,

H8S/2368F, H8S/2378RF, H8S/2377RF, and the E10A Emulator

1. When the E10A emulator system is initiated, it initializes the general registers and part of the

control registers as shown in table 2.1.

ER0 to ER6 H’0

ER7 (SP) H'10

CCR 1 for I mask, and others undefined

EXR H’7F

2. System Control Register

In the E10A emulator, the internal I/O registers can be accessed from the [IO] window.

However, be careful when accessing the system control register. The E10A emulator saves the

program is executed. Since this is done during a break, do not rewrite the system control

3. Memory Access during Emulation

If the memory contents are referenced or modified during emulation, realtime emulation

cannot be performed because the user program is temporarily halted.

4. The E10A emulator communicates with the H8S/2378F by using the PG4, P53, WDTOVF#,

RES#, PG5, and PG6 pins. These pins cannot be used.

5. The power consumed by the MCU can reach several mA. This is because the user power

supply drives one HD74LV125A to make the communication signal level match the user-

system power-supply voltage.

6. Do not use an MCU that has been used for debugging.

If the flash memory is rewritten many times, and the MCU is left for a few days, data may be

lost due to retention problems.
