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 value 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)
