The Clocks tab is intended to simplify the selection of input clock frequencies and the
source of internal clocking signals. For further information regarding clocking and clock
sources, refer to the S1D13505 Hardware Functional Specification, document number
X23A-A-001-xx.
In automatic mode the values are calculated based on either the LCD or CRT tab settings.
In this mode, the required frequencies for the input clocks are displayed in blue in the
"Auto" section of each group. It is the responsibility of the system designer to ensure that
the correct CLKI frequencies are supplied to the S1D13505.
Making a selection other than "Auto" indicates that the value for CLKI is known and is
fixed by the system design. Options for LCD and CRT frame rates are limited to ranges
determined by the clock values.
Note
Changing clock values may modify or invalidate Panel or CRT settings. Confirm all set-
tings on these two tabs after changing any clock settings.
