157 / 179 page  157/179 ST92141 - ELECTRICAL CHARACTERISTICS DC ELECTRICAL CHARACTERISTICS (VDD = 5V ± 10%, TA = –40°C to +85°C, unless otherwise specified) Note: (1) Unless otherwise stated, typical data are based on TA=25°C and VDD=5V. They are only reported for design guidelines - not tested in pro- duction. (2) Data based on characterization results - not tested in production. (3) For a description of the EMR1 Register - BSZ bit refer to the Device Configuration Registers Chapter.
