FUNCTIONAL DESCRIPTION
System Interface
The S6D0110 has five high-speed system interfaces: an 80-system 16-bit/8-bit bus, a 68-system 16-bit/8-bit bus,
and a serial interface (SPI: Serial Peripheral Interface port). The IM2-0 pins select the interface mode.
The S6D0110 has three 16-bit registers: an index register (IR), a write data register (WDR), and a read data register
(RDR). The IR stores index information for control register and GRAM. The WDR temporarily stores data to be
written into control register and GRAM. The RDR temporarily stores data read from GRAM. Data written into the
GRAM from the MPU is first written into the WDR and then written into the GRAM by internal operation automatically.
Data is read through the RDR when reading from the GRAM, and the first read data is invalid and the second and
the following data are valid.
When a logic operation is performed inside of the S6D0110 by using the display data stored in the GRAM and the
data written from the MPU, the data read through the RDR is used. Accordingly, the MPU does not need to read data
twice nor to fetch the read data into the MPU. This enables high-speed processing.
Execution time for instruction, except oscillation start, is 0-clock cycle so that instructions can be written in
succession.

Bit Operation
The S6D0110 supports the following functions: a write data mask function that selects and writes data into the
GRAM in bit units, and a logic operation function that performs logic operations or conditional determination on the
display data set in the GRAM and writes into the GRAM. With the 16-bit bus interface, these functions can greatly
reduce the processing loads of the MPU graphics software and can rewrite the display data in the GRAM at high
speed. For details, see the Graphics Operation Function section.
