( 8 out of the 34 LCD driver outputs can be used as
output-only ports by mask option. )

LCD driver
: 34 outputs
(1) At 1/4 duty and 1/3 bias
: 120 segments (max.)
(2) At 1/3 duty and 1/3 bias
: 93 segments (max.)
(3) At 1/2 duty and 1/2 bias
: 64 segments (max.)
Voltage Regulator for LCD Driver (selectable by mask option)
The LCD panel display is stable regardless of temporary supply voltage drop, because the voltage
generated by the voltage regulator for LCD driver is supplied to the bias voltage generator as a
reference voltage.
LCD Operating Voltage
When the voltage regulator for LCD driver is used
: 3.6 V ( Duty cycle = 1/4 or 1/3 )
: 2.4 V ( Duty cycle = 1/2 )
When the voltage regulator for LCD driver is not used
: 4.5 V ( Duty cycle = 1/4 or 1/3 )
: 3.0 V ( Duty cycle = 1/2 )
