CSES
0
No wait access
1
Cycle steal access
Status register for identifying active or inactive in
cycle steal function.
Set "1" during active with cycle steal function.
CSES is for only reading, not for writing.
0
D6
RESET
0
Reset OFF
1
Reset ON
Software reset.
Surely return to reset off after reset on.

0
1/16 Division
Set the division of OSC clock for internal operation
from OSC1 input pin.
When reset, OSCC = 000, OSC1 clock doesn't
divide.
Don't set except left table.
000
D2
DISP
0
Display OFF
1
Display ON
Control the displaying ON/OFF of LCD.
When reset, DISP = 0, set display OFF.
REV (D1) set "1", and when DISP = "0" display data
UD <3:0> output "1" in reversal mode.
0
D1
REV
0
Normal display
1
Reversal display
Control normal/reversal of LCD display.
When reset, REV = 0, set normal display.
In using LCD of permeation method, REV = "1" has
effect.
0
00000
R/W
D7 = Only "R"
D0
LCDE
0
LCDENB = "0" output
1
LCDENB = "1" output
Set the output data from LCDENB output pin.
When reset, LCDE = 0, LCDENB output "0" (Vss
potential).
This function is prepared for controlling the voltage
of LCD.
When the power supply is ON after finish each
register setting, LCDE = "1", supply voltage of LCD.
Conversely for setting power supply OFF, first LCDE
= "0", the voltage of LCD is OFF. Therefore enable
to prevent LCD from being unusual voltage as DC.
This function use for satisfy the need of LCD.
