ENABLE CONFIGURATIONS THROUGH THE 20 PIN
HEADER
The following diagram shows how to enable or disable differ-
ent regulators by jumpering pins in the 20 pin header.
One practical use of grounding the enable pins of the regula-
tors is to signal a System Delay Sequence (EN_T). One

practical use of grounding the enable pins of the regulators is
to signal a System Delay Sequence (EN_T). Powering the
chip through EN_T assertion is described in more detail in the
“Power On” section of the datasheet.
