(3) D5 KT (Key scan time) Key scan time select bit
1: 10ms
0: 5ms
This bit selects the key scan cycle time. In the case of a 740kHz oscillating frequency, writing a
“1” to this bit sets the key scan cycle time at 10ms, writing a “0” sets the key scan cycle time at
5ms. Even if the
RESET
pin is pulled to a “L” level, the value of this bit will not change.
(4) D1 to D0 DTY (Display duty select bit)
This bit selects the display duty. The correspondence between each bit and display duty is shown
in the chart below. Even if the
RESET
pin is pulled to a “L” Level, the values of these bits will not
change.

(1) D0 DISP (Display ON/OFF mode bit)
1: Display ON mode
0: Display OFF mode
This bit selects whether the display is ON or OFF. Writing a “1” to this bit selects the display ON
mode. Writing a “0” to this bit selects the display OFF mode. At this time, the COM and SEG pins
will be at the VSS level. Even if this bit is set to “0”, the display RAM contents will not change.
If the
RESET
pin is pulled to a “L” level, this register is reset to “0”.
(2) D2 to D5 T1 to T4 (Test mode select bit)
These bits are used to test the IC. “0” must be written to these bits.
