2.1 Interfaces Parameter Definitions
Symbol Description
AI Analog input
AO Analog output
B Bidirectional digital with CMOS input
CSI Supply voltage for MIPI_CSI circuits and I/O; (1.2 V for low power mode)
DI Digital input(CMOS)
DSI Supply voltage for MIPI_CSI circuits and I/O;(1.2 V for low power mode)

nppdpukp
Programmable pull resistor. The default pull direction is indicated using capital letters
and is a prefix to other programmable options:
NP: pdpukp = default no-pull with programmable options following the colon (:)
PD: nppukp = default pull-down with programmable options following the colon (:)
PU: nppdkp = default pull-up with programmable options following the colon (:)
KP: nppdpu = default keeper with programmable options following the colon (:)
KP Contains an internal weak keeper device (keepers cannot drive external buses)
MIPI Mobile industry processor interface
NP Contains no internal pull
OD Open drain
PD Contains an internal pull-down device
PI Power input
PO Power output
