6.6 TIMER CHARACTERISTICS
(TA = -40 to +85°C unless otherwise specified)
Note*: When available.
6.7 SPI CHARACTERISTICS
(TA = -40 to +85°C unless otherwise specified)
6.8 LCD ELECTRICAL CHARACTERISTICS
(TA = -40 to +85°C unless otherwise specified)
Notes:
1. The DC offset refers to all segment and common outputs. It is the difference between the measured voltage value and nominal valu e for
every voltage level.
2. An external resistor network is required when VLCD is lower then 4.5V.
6.9 PSS ELECTRICAL CHARACTERISTICS (When available)
(TA = -40 to +85°C unless otherwise specified
