REGISTER SUPPLEMENTARY DESCRIPTION
(1) Setting external clock input mode (by use of EXCK0 (12016) and
EXCK1 (12316))
Two modes given below are available for the external clock sig-
nal input. (the settings (EXCK1, EXCK0) = (0, 1), (1, 0) are forbid-
den.)
(a) When (EXCK1, EXCK0) = (0, 0), FOSC = 20 to 30 MHz
Input from the TCK pin a constant-period continuous external
clock that synchronizes with the horizontal synchronization signal.
And input from HOR pin a constant-period continuous horizontal
synchronous signal.
Never stop inputting the clock while displaying.
Do not have to set a display frequency because the clock just as
it is entered from outside is used as the display clock.
(b) When (EXCK1, EXCK0) = (1, 1), FOSC = 20 to 80 MHz
Input from the TCK pin a constant-period continuous external
clock that synchronizes with the horizontal synchronization signal.
Never stop inputting the clock while displaying.
Be sure to set a display frequency because the internal clock
made to synchronize with the clock input from outside is used as
the display clock (see the next page).
