Information regarding change of names mentioned
within this document, to Renesas Technology Corp.
On April 1st 2003 the following semiconductor operations were transferred to
Renesas Technology Corporation: operations covering microcomputer, logic,
manalog and discrete devices, and memory chips other than DRAMs (flash
memory, SRAMs etc.).
oAccordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other
.cHitachi brand names are mentioned in the document, these names have all
been changed to Renesas Technology Corporation.
Except for our corporate trademark, logo and corporate statement, no
Uchanges whatsoever have been made to the contents of the document, and
t4these changes do not constitute any alteration to the contents of the
document itself.
eThank you for your understanding.

Dummy gate output. When CAD bit is high,
output VGH and Vgoff level. When CAD bit is
low, output Vgoff level. When these pins are
not used, leave them open.
Notes: 1. Signal names 1/2 are equivalent inputs. Supply the reset signal to either, and leave the
other open.
2. The quantity does not match the number of pads.

HD66775
Instructions
Outline
HD66775 has three internal registers. The data is written on to these registers by using a gate serial
data interface. This interface can be directly connected to the HD66770 or HD66772 source driver for
an automatic transfer of instructions. When an instruction is written on to HD66770/772 via the bus
from the CPU, it is output from the serial interface of HD66770/772, and HD66775 receives the
instruction to adjust the settings of one of its internal registers.
When the display system uses two HD66775s, the same instructions are transferred to both. Both
HD66775s use the master/slave function to scan the gate line as well the LSI in this case is scanned.
In the bit configuration for the transfer of instructions, the upper three bits are index numbers that
indicate the target register of the transfer, and the lower 13 bits are the data. This interface is
common for HD66775 and HD667P00. Index numbers R00h to R02h are instructions for HD667P00,
SLP and GON of R00h, and numbers R06h to R07h are instructions for HD66775.

SLP: When SLP = 1, the HD66775 is in the sleep mode. G1 to G120 and GTEST1 and GTEST2 are
output as GND. However, the register settings are kept. For details, refer to the target specifications
of the HD66770/772.
GON: When GON = 0 and DISPTMG = 0, G1 to G120 and GTEST1 and GTEST2 are output as
GND. When GON = 1, G1 to G120 are normally output. For the display on/off flow, refer to the
section of the instruction setting flow of the HD66770/772.
