Pins

Names

Description

28,32,36

PPS 1-3

Output of the Programmable Supplies

40

PPS 4

Output of the Fast DAC Programmable Power Supply

27,31,35,39

Isense_PP1-4

Outputs (Driver outputs before Rsens) for current evaluations. These outputs could be used

to connect to the analog comparators in order to create fast digital signals based on

current.
