Revision 1.0
4.2 Clocks
The clock for the S1D13L03 Simple LCD Controller is provided by a 4MHz oscillator.
Note
The on-board 4MHz oscillator is not specified to work below a 3.0V supply voltage.
The S1D13L03 can output the input clock on the CLKOUT pin depending on the state of
the CLKOUTEN input. Both these signals are available on the H4 connector: CLKOUT on
pin 1 and CLKOUTEN on pin 4. On the board the CLKOUTEN pin is pulled down which
disables the CLKOUT signal.
Note
H4 connector is not mounted. There is an allocated area for mounting.
4.3 Reset
The S1D13L03 Simple LCD Controller on the S5U13L03P00C100 Evaluation Board can
be reset using a push-button (SW2), or via an active low reset signal from the host devel-
opment platform (pin 33 on the H1 connector).
Note
H1 connector is not mounted. There is an allocated area for mounting..
4.4 Power Save
The S1D13L03 chip has an input called PWRSVE that will enable (when high) or disable
(when low) the power save mode. This signal is available on pin 5 of the H4 connector. On
the board the PWRSVE pin is pulled down which means power save mode is controlled
only by the S1D13L03 register setting.
Note
H4 connector is not mounted. There is an allocated area for mounting.
