LCD Display RAM
The 12-byte area of address 0040
16
to 004B
16
is the designated
RAM for the LCD display. When
“
1
”
is written to these addresses, the
corresponding segments of the LCD display panel are turned on.
LCD Drive Timing
For the LCD drive timing, type A or type B can be selected.
The LCD drive timing is selected by the timing selection bit (bit 4 of
LCD mode register).
Type A is selected by setting the LCD drive timing selection bit to
“
0
”
,
type B is selected by setting the bit to
“
1
”
. Type A is selected after
reset.
The LCDCK timing frequency (LCD drive timing) is generated inter-
nally and the frame frequency can be determined with the following
equation;
I
Note
(1) When the STP instruction is executed, the following bits are
cleared to
“
0
”
;
LCD enable bit (bit 3 of LCD mode register)
Bits other than bit 6 of the LCD power control register.
(2) When the voltage is applied to V
L1
to V
L3
by using the external
resistor, write
“
10
2
”
to dividing resistor for LCD power selection bits
(RSEL) of the LCD power control register (address 38
16
).
