Keep safety first in your circuit designs! 1. Renesas Technology Corp. puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammabl

1.2 Connecting the Emulator with the User System To connect the E10A-USB emulator (hereinafter referred to as the emulator), the H-UDI port connector must be installed on the user system to connect the user system interface cable. When designing the user system, refer to the recommended circuit between the H-UDI port connector and the MPU. In addition, read the E10A-USB emulator user's manual and hardware manual for the related device. Table 1.2 shows the type number of the emulator, the

1.5 Recommended Circuit between the H-UDI Port Connector and the MPU 1.5.1 Recommended Circuit (36-Pin Type) Figure 1.3 shows a recommended circuit for connection between the H-UDI and AUD port connectors (36 pins) and the MPU 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 MPMD pin must be 0 when the emulator is connected and 1 when the emulator is not connected, respectively. (1) When the emulator is used: MPMD = 0 (

Section 2 Software Specifications when Using the SH7343 2.1 Differences between the SH7343 and the Emulator 1. When the emulator system is initiated, it initializes the general registers and part of the control registers as shown in table 2.1. The initial values of the actual SH7343 registers are undefined. When the emulator is initiated from the workspace, a value to be entered is saved in a session. Table 2.1 Register Initial Values at Emulator Link Up Register Emulator at Link U

3. Low-Power States (Sleep, Software Standby, Module Standby, U Standby, and R Standby) For low-power consumption, the SH7343 has sleep, software standby, module standby, U standby, and R standby states. The sleep, software standby, and module standby states are switched using the SLEEP instruction. When the emulator is used, the sleep and software standby states can be cleared with either the normal clearing function or with the [STOP] button, and a break will occur. Note: The memory mus

8. Cache Operation during User Program Break When cache is enabled, the emulator accesses the memory by the following methods: • At memory write: Writes through the cache, then issues a single write to outside. The LRU is not updated. • At memory read: Reads memory from the cache. The LRU is not updated. Therefore, when memory read or write is performed during user program break, the cache state does not change. • At breakpoint set: Disables the instruction cache. 9. Port G The AUD pin

12. Memory Access during Break In the enabled MMU, when a memory is accessed and a TLB error occurs during break, it can be selected whether the TLB exception is controlled or the program jumps to the user exception handler in [TLB Mode] in the [Configuration] dialog box. When [TLB miss exception is enable] is selected, a “Communication Timeout error” will occur if the TLB exception handler does not operate correctly. When [TLB miss exception is disable] is selected, the program does not j
