IO_OUTP_CTRL 1-3
The outputs are controlled via 3 advanced feature registers.
Only board level cameras: The outputs are controlled via 4 advanced feature
registers.
The Polarity field determines whether the output is inverted (1) or not (0).
The Output mode can be viewed in the table below. The current status of the
output can be queried and set via the PinState .
It is possible to read back the status of an output pin regardless of the output
mode. This allows for example the host computer to determine if the camera
is busy by simply polling the BUSY output.
Register Name Field Bit Description
0xF1000320 IO_OUTP_CTRL1 Presence_Inq [0] Indicates presence of this fea-
ture (read only)
PWMCapable [1] Only Guppy board level cameras:
Indicates if an output pin sup-
ports the PWM feature.
See Table 49: PWM configura-
tion registers on page 117.
