P/
S
This is the pin for selecting parallel data input or serial data input.
P/
S
= "H": Parallel data input.
P/
S
= "L": Serial data input.
The pins of the LSI have the following functions depending on the state of
P/
S
input.
When P/
S
is "L", D0 to D5 will go into the Hi-Z state. In this condition,
the data on the lines D0 to D5 can be "H", "L", or open. The pins
RD
(E)
and
WR
(R/
W
) should be tied to either the "H" level or the "L" level.
During serial data input, it is not possible to read the display data in the
RAM.
This is the pin for selecting whether to enable or disable the internal
oscillator circuit for the display clock.
CLS = "H": The internal oscillator circuit is enabled.
CLS = "L": The internal oscillator circuit is disabled (External input).
When CLS = "L", the display clock is input at the pin CL.
This is the pin for selecting whether master operation or slave operation
is made towards the ML9050/9051. During master operation, the
synchronization with the LCD display system is achieved by inputting the
timing signals necessary for LCD display.
M/
S
= "H": Master operation
M/
S
= "L": Slave operation
The functions of the different circuits and pins will be as follows
depending on the states of M/
S
and CLS signals.
