Section 1 Overview The H8S/2678 series, H8S/2678R series, H8S/2668 series, H8S/2368 series, H8S/2378 series E6000 emulator (hereafter referred to as the E6000) is an efficient software and hardware development support tool for application systems using Hitachi's original microcomputers H8S/2678 series, H8S/2678R series, H8S/2668 series, H8S/2368 series, H8S/2378 series. 1.1 Environment Conditions Table 1.
1.2 Supported MCUs and User System Interface Cables Tables 1.2 shows the correspondence between the MCUs and the user system interface cables supported by the E6000. Table 1.2 H8S/2678 Series, H8S/2678R Series, H8S/2668 Series, H8S/2368 series, H8S/2378 series MCUs and User System Interface Cable No.
1.3 Operating Voltage and Frequency Specifications Table 1.3 shows the MCU operating voltage and frequency specifications supported by the E6000. If the E6000 is used in an environment that exceeds the operating voltage range and operating frequency range guaranteed for the MCU operation, normal emulator operation is not guaranteed. Table 1.3 Operating Voltage and Frequency Specifications MCU Types Operating Voltage (V) Operating Frequency (φ) (MHz) H8S/2678 Series 3.0-3.
In the E6000, the clock can be selected by using the Configuration window or the Clock command. Table 1.4 Clock Selections Clock Command Parameter Configuration Window Setting 12 25 33 t t2 12.5 MHz internal clock 25 MHz internal clock 33 MHz internal clock Target Target/2 Notes Default Not supported by the actual MCU. Use this clock only when the required clock duty cannot be obtained.
Section 2 User System Interface All user system interface signals are directly connected to the MCU in the E6000 with no buffering except for those listed below which are connected to the MCU through control circuits: • • • • • • NMI RESET MD2, MD1, MD0 XTAL EXTAL WAIT 2.1 Signal Protection All user system interface signals are protected from over- or under-voltage by use of diode arrays except for the AVcc and Vref.
Default: Figure 2.1 Default User System Interface Circuit Mode Pins (MD2, MD1 and MD0), NMI, and WAIT: The NMI signal is input to the MCU through the emulator control circuit. The rising/falling time of the NMI signal must be 8 ns/V or less. The mode pins are only monitored. The CPU mode depends on the HDI Configuration settings. Figure 2.2 User System Interface Circuit for MD2, MD1, MD0, NMI, and WAIT RESET: Figure 2.
P40 to P47 (pins used for AN0 to AN7 and DA0 to DA1), P54 to P57 (pins used for AN12 to AN15 and DA2 to DA3) Vcc, AVcc, AVss, and Vref: Pins P50 to P57 are also used for interrupt inputs. When the user system is not connected and pull-up resistors are removed, input will be undefined and may illegally detect an interrupt. When P50 to P57 are used to input interrupt signals, it is recommended to connect the pull-up resistors to these pins. Figure 2.

Section 3 Notes on Use 3.1 I/O Register Differences between Actual MCU and E6000 In the E6000, one evaluation chip emulates several types of MCU. Therefore, there are some differences in I/O registers between an actual MCU and the E6000. Note these differences when accessing the I/O registers. I/O port is in the input state at default. The I/O register contents indicate the emulator port status. When the user system interface cable is not connected, the read value is 1 due to the E6000 pullup resistors.
3.3 Use of an Internal RAM Area as External Memory An internal RAM area can be used as an external address when the RAME bit of the SYSCR is cleared to "0". Emulator (option memory) cannot be selected for the internal RAM area. Only user memory can be accessed as an external address. Option memory cannot be accessed as an external address. In this case, Memory Mapping setting is the same as the Internal RAM setting. 3.
Section 4 HDI Parameters 4.1 Address Areas Table 4.1 lists the parameters for address areas (Area) that can be specified with HDI command line interface or displayed as trace results. Table 4.1 Address Area Parameters HDI Parameter (Trace Display) Address Area Description rom On-chip ROM MCU's on-chip ROM, which can be read but cannot be written to. ram On-chip RAM MCU's on-chip RAM (except for DTC RAM), which can be read and written to.
4.2 Access Status Table 4.2 lists the parameters for access status (Status) that can be specified with HDI command line interface or displayed as trace results. Table 4.2 Access Status Parameters HDI Parameter (Trace Display) Access Status Description dmac On-chip DMAC Access by the MCU's DMAC (Cannot be accessed by the EXDMA controller.
