Section 1 Connecting the Emulator with the User System 1.5 1.5.1 Recommended Circuit between the H-UDI Port Connector and the MCU Recommended Circuit (14-Pin Type) Figure 1.2 shows a recommended circuit for connection between the H-UDI port connector and the MCU when the emulator is in use. Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector. 2. The _ASEMD0 pin must be 0 when the emulator is connected and 1 when the emulator is not connected, respectively.
Section 1 Connecting the Emulator with the User System When the circuit is connected as shown in figure 1.2, the switches of the emulator are set as SW2 TM = 1 and SW3 = 1. For details, refer to section 3.8, Setting the DIP Switches, in the SuperH Family E10A-USB Emulator User’s Manual. Vcc = I/O power supply All pulled-up at 4.

Section 2 Software Specifications when Using the SH7125 or SH7124 Section 2 Software Specifications when Using the SH7125 or SH7124 Group 2.1 Differences between the MCU and the Emulator 1. When the emulator system is initiated, it initializes the general registers and part of the control registers. The initial values of the MCU are undefined. When the emulator is initiated from the workspace, a value to be entered is saved in a session. Table 2.
Section 2 Software Specifications when Using the SH7125 or SH7124 5. Memory Access during User Program Execution During execution of the user program, memory is accessed by the following two methods, as shown in table 2.2. Table 2.2 Memory Access during User Program Execution Method Description H-UDI read/write The stopping time of the user program is short because memory is accessed by the dedicated bus master. Short break This method is not used in this product. (Do not set short break.

Section 2 Software Specifications when Using the SH7125 or SH7124 2.2 2.2.1 Specific Functions for the Emulator when Using the SH7125 or SH7124 Group Event Condition Functions The emulator is used to set event conditions for the following function: • Break of the user program Table 2.6 lists the types of Event Condition. Table 2.
Section 2 Software Specifications when Using the SH7125 or SH7124 Table 2.7 lists the combinations of conditions that can be set under Ch1 to Ch10. Table 2.
Section 2 Software Specifications when Using the SH7125 or SH7124 Sequential Setting: Using the [Combination action (Sequential PtoP)] dialog box specifies the sequential condition. Table 2.8 Conditions to Be Set Classification Item [Ch1, 2, 3] list box Sets the sequential condition and the start or end of performance measurement using Event Conditions 1 to 3. [Ch4, 5] list box Description Don’t care Sets no sequential condition or the start or end of performance measurement.
Section 2 Software Specifications when Using the SH7125 or SH7124 The program is executed up to the condition of Ch1 and halted. Here, the condition is satisfied in the order of Ch3 -> 2 -> 1. Figure 2.1 [Source] Window at Execution Halted (Sequential Break) If the sequential condition, performance measurement start/end, or point-to-point for the internal trace is set, conditions of Event Condition to be used will be disabled.
Section 2 Software Specifications when Using the SH7125 or SH7124 5. If the settings of the Event condition or the sequential conditions are changed during execution of the program, execution will be suspended. (The number of clocks to be suspended during execution of the program is a maximum of about 52 bus clocks (Bφ). If the bus clock (Bφ) is 10.0 MHz, the program will be suspended for 5.2 μs.) 6.
Section 2 Software Specifications when Using the SH7125 or SH7124 5. If an address of a BREAKPOINT cannot be correctly set in the ROM or external flash memory area, a mark z will be displayed in the [BP] area of the address on the [Source] or [Disassembly] window by refreshing the [Memory] window, etc. after Go execution. However, no break will occur at this address. When the program halts with the event condition, the mark z disappears. 2.2.
