For low-power consumption, the SH7751R has sleep, standby, and module standby modes.
The sleep and standby modes are switched using the SLEEP instruction. When the emulator is
used, the sleep and standby modes can be cleared by either normal clearing or with the [Stop]
button. Note that, however, if a command has been entered in standby mode or module
standby mode, the TIMEOUT error is displayed.
The SH7751R RESET signals (/RESET and /MRESET) are only valid during emulation
started with clicking the GO or STEP-type button. If these signals are input from the user
system in command input wait state, they are not sent to the SH7751R.
The DMAC operates even in the command wait state. When a data transfer request is
generated, the DMAC executes DMA transfer.
In the emulator, the internal I/O registers can be accessed from the [I/O Registers] window.
However, pay attention when accessing the SDMR register of the bus-state controller. Before
accessing the SDMR register, specify addresses to be accessed in the I/O-register definition
file (SH7751R.IO) and then activate the HDI. For details on I/O-register definition files, refer
to the Hitachi Debugging Interface User's Manual.
When a memory is accessed from the memory window, etc. during user program execution,
the user program is resumed after it has stopped in the E10A emulator to access the memory.
Therefore, realtime emulation cannot be performed.

following the SLEEP instruction.
6 to use [Step…] from the [Run] menu. If [Rate] is 5 or less, a Communication
timeout error occurs.
If the memory is accessed or modified in sleep mode, the sleep mode is cleared
and execution starts at the instruction following the SLEEP instruction.
If the state transits to the hardware standby mode, a TIMEOUT error occurs.
When the SLEEP instruction is executed by STEP-type commands, set [Rate] to
