1 The minimum/maximum specifications are guaranteed over the −40°C to +85°C temperature range (TMIN to TMAX).
2 Guaranteed by characterization.
3 Refers to all I2C pins (DDC and control port).
4 The prefix x refers to pin names beginning with S, DDCA_S, and DDCB_S.
5 CP timing figures were obtained using the maximum drive strength value (0x3F) in User Map Register 0xF4.
6 The suffix x refers to pin names ending with 0, 1, 2, and 3.
