Functions
C / D
Input
WR
= L ······ C / D = H: Command Write
C / D = L: Data Write
RD = L ······ C / D = H: Status Read
C / D = L: Data Read
HALT
Input
H ······ Normal, L ······ Stops the oscillation of the clock
RESET
Input
H ······ Normal (T6963CFG has internal pull
up resistor)
L ······ nitialize T6963CFG. Text and graphic have addresses and text and graphic area settings are
retained.
DSPON
Output
Control pin for external DC / DC. DSPON is L when
HALT
is L or RESET is L.
(When DSPON goes H, the column drivers are cleared.)
