For low-power consumption, the SH7616 has sleep and standby modes.
The sleep and standby modes are switched using the SLEEP instruction. The sleep mode can
be cleared by either normal clearing or by the satisfaction of a break condition (including
(BREAK) or (CTRL) + C key input). In the latter case, the user program breaks. The standby
mode can be cleared with the normal clearing function or (BREAK) or (CTRL) + C key input,
and after the standby mode is cleared, the user program operates correctly. Note that,
however, if a command has been entered in standby mode, no commands can be used from the
emulator after the standby mode is cleared. The states cannot be canceled by the [Stop]
button.
The SH7616 /RES signal is only valid during user program execution 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 SH7616.
The DMAC operates even while the emulation is executed or while the emulator is waiting for
command input. When a data transfer request is generated, the DMAC executes DMA
transfer.
While the emulator is executing the user program, any interrupt to the SH7616 can be used.
While the emulator is waiting for command input, interrupts are not processed. However, if an
edge sensitive interrupt occurs in command input wait state, the emulator holds the interrupt
and executes the interrupt processing routine when the GO command is entered.
windows.
If the value of the frequency change register is changed during watchdog timer operation, use
the window other than the [I/O Registers] window or [Memory] window.
When accessing the reserved memory area, use the [Memory] window; do not use other
The watchdog timer operates only while the user program is being executed.
2. If the memory is accessed or modified in sleep mode, the sleep mode is cleared and
signals (/RES, /WAIT, and /BRLS) are being low. A TIMEOUT error will occur.
