Input/output pin control
All input and output signals running over the camera I/O connector are con-
trolled by an advanced feature register.
IO_INP_CTRL 1-2
The Polarity flag determines whether the input is low active (0) or high
active (1). The input mode can be seen in the following table. The PinState
flag is used to query the current status of the input.
Register Name Field Bit Description
0xF1000300 IO_INP_CTRL1 Presence_Inq [0] Indicates presence of this
feature (read only)
--- [1..6]
Polarity [7] 0: low active

• For inputs the PinState bit refers to the inverted out-
put side of the optical coupler. This signals that an
open input sets the PinState bit to 1.
