3. Low-Power States (Sleep, Standby, and Module Standby)
Notes: 1. After the sleep mode is cleared by a break, execution restarts at the instruction
4. Reset Signals
Note: Do not start user program execution while pins /RESET, /MRESET, /BREQ, and /RDY
5. Direct Memory Access Controller (DMAC)
6. Memory Access during User Program Execution

For low-power consumption, the SH7750R 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 by the [Stop]
button. In the latter case, the user program breaks. Note, however, that if a command has been
entered in standby mode or module standby mode, a TIMEOUT error will occur.
The SH7750R reset signal is only valid during emulation started with clicking the GO or
STEP-type button. If this signal is input from the user system in command input wait state, it
is not sent to the SH7750R.
The DMAC operates even when the emulator is used. When a data transfer request is
generated, the DMAC executes DMA transfer.
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.
The stopping time of the user program is as follows:
Environment:
When a one-byte memory is read from the command-line window, the stopping time will be
about 8 ms.
2. If the memory is accessed or modified in sleep mode, the sleep mode is cleared and
3. If an operation such as the command input is performed in the hardware standby state,
4. When the SLEEP instruction is executed by a step command and [Step…] in the [Run]
are being low. A TIMEOUT error will occur.

following the SLEEP instruction.
execution starts at the instruction following the SLEEP instruction.
the command from the emulator cannot be used, or the state cannot be cancelled by the
[Stop] button.

will occur.
