For low-power consumption, the SH7705 has sleep, software standby, and module standby states.
The sleep, software standby, and module standby states are switched using the SLEEP instruction.
When the emulator is used, only the sleep state can be cleared with either the normal clearing
function or with the [Stop] button, and a break will occur.
Note: The memory must not be accessed or modified in sleep state.
The SH7705 reset signals 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 SH7705.

When the emulator system is initiated, it initializes the general registers and part of the control
registers as shown in table 6.2. The initial values of the actual SH7705 registers are undefined.
The emulator uses the Hitachi-UDI; do not access the Hitachi-UDI.
