9.3 Fast General Purpose Input
The operating modes of the video/data output router are set by the VDO_MODE
MMIO register. A subset of the operating modes is presented in

module, while
the FGPO module.
A subset of the VDO pins can individually be set to operate as GPIO pins in case they
are not used for their primary video/streaming data function.
The Fast General Purpose Input (FGPI) captures data in a variety of modes:
•

QVCP function
TFT LCD controller with 24- or 18-
bit digital RGB output and
associated control signals.
Digital ITU 656 YUV 8-/10-bit and
Hsync, Vsync and Cblank signals.
Digital 16-bit YUV and Hsync,
Vsync and Cblank signals.
Digital 20-bit YUV and Hsync,
Vsync and Cblank signals.
Digital 24-bit YUV or RGB and
Hsync, Vsync and Cblank signals.
Digital 30-bit YUV or RGB and
Hsync, Vsync and Cblank signals.
Digital ITU 656 YUV 8-bit
n/a
raw mode 8 or 16-bit parallel data. The data is continuously captured as soon as
enabled, and is written to memory using double buffering to prevent loss of data
8-, 16- or 32-bit message passing between PNX17xx Series’s. Messages of up to
16 MB in length are received and written to memory. Upon completion, an
interrupt is generated, and the FGPI switches to the next software input buffer.
8-, 16- or 32-bit structured data capture. Data is captured in records, using the
REC_START signals to designate when records are started. The BUF_START
signal can, optionally, be used to force a software buffer switch. This mode can be
used to capture 2-dimensionally structured data, such as raw video samples.

briefly describes the data streaming/generation features of
FGPO function
3- or 8-bit data streaming.
FGPO is usually set in 8-bit mode.
19-bit data streaming.
FGPO is usually set in 16- or 32-bit mode, but only
the 19 lower bits are output per 16- or 32-bit words.
13-bit data streaming.
FGPO can be set in 8-, 16- or 32-bit mode, but only
the 13 lower bits are output per 8-, 16- or 32-bit
words.
9-bit data streaming.
FGPO is usually set in 8- or 16-bit mode, but only the
9 lower bits are output per 8- or 16-bit words.
5-bit or 8-bit data streaming.
FGPO is usually set in 8-bit mode

24-bit data streaming.
FGPO is actually set in 32-bit mode but only the 24
lower bits are output per 32-bit words.
32-bit data streaming.
