LCDA Module

Function

Higher current consumption when using shared LCD ports as fast toggling outputs

Description

If a shared LCD pin (segment or com line) is used as digital fast toggling output (f>10kHz) and the VLCD is >0V (BG enabled) the device current consumption increases with higher toggling frequencies.

Workaround

1. Do not use shared LCD pins as fast toggling outputs if an LCD is used.
2. Reduce the toggle frequency of the shared pin to <10kHz.
