The following sections describe the contents of each control word.
Output Inversion: When Output Inversion is disabled, all A and B output drivers of the SSTE32882KA1 are driven to the same
levels.
Output Inversion may be enabled to conserve power, reducing simultaneous switching output currents in the SSTE32882KA1.
When Output Inversion is enabled, all A outputs will follow the equivalent inputs, however the following B outputs will be
driven to the complement of the matching A output: QBA03-QBA9, QBA11, QBA13 - QBA15, QBBA0 - QBBA2. Output
Inversion does not affect SSTE32882KA1 control word programming.
Output floating refers to allowing many A/B outputs to enter a hi-Z state when they are not being used. This is to conserve
power when the outputs are resistively terminated to a voltage (e.g., V
following outputs (on both matching A and B outputs) are hi-Z when not actively driven: QxAn, QxBAn, QxRAS, QxCAS,
and QxWE. Output floating is independent of Output Inversion and does not affect SSTE32882KA1 control word
programming.
