Technical Manual
8.2.1.13. AP
Defines the horizontal address range of the virtual screen.
APL is the least significant byte of the address.
Figure 8. AP and C/R relationship
8.2.2. SLEEP IN
Places the system in standby mode. This command has no
parameter bytes. At least one blank frame after receiving
this command, the S1D13305F halts all internal opera-
tions, including the oscillator, and enters the sleep state.

AP
Blank data is sent to the X-drivers, and the Y-drivers have
their bias supplies turned off by the YDIS signal. Using
the YDIS signal to disable the Y-drivers guards against
any spurious displays.
The internal registers of the S1D13305 series maintain
their values during the sleep state. The display memory
control pins maintain their logic levels to ensure that the
display memory is not corrupted.
The S1D13305 series can be removed from the sleep state
by sending the SYSTEM SET command with only the P1
parameter. The DISP ON command should be sent next
to enable the display.
Figure 9. SLEEP IN instruction
1. The YDIS signal goes LOW between one and two
frames after the SLEEP IN command is received.
Since YDIS forces all display driver outputs to go to
the deselected output voltage, YDIS can be used as a
power-down signal for the LCD unit. This can be
done by having YDIS turn off the relatively high-
power LCD drive supplies at the same time as it
blanks the display.
2. Since all internal clocks in the S1D13305 series are
halted while in the sleep state, a DC voltage will be
applied to the LCD panel if the LCD drive supplies
remain on.
If reliability is a prime consideration, turn off the
LCD drive supplies before issuing the SLEEP IN
command.
3. Note that, although the bus lines become high imped-
ance in the sleep state, pull-up or pull-down resistors
on the bus will force these lines to a known state.
