Chapter 2: Overview
• Broadcast of messages to 1 or more receiving PNX15xx Series’s.
• Message or unstructured data transmission is in 8-, 16- or 32-bit parallel format,
with data rates up to 100 MHz, providing an aggregate data rate of up to 400
MB/s.
The VDO pins consist of 39 pins, split into 32 data pins, 2 clock pins and 4 control
signals.
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 Table 7. A complete
behavior description of the output router is available in Section 7. on page 3-16.
Section 7.5 provides a description of the Video generation capabilities of the QVCP
module, while Section 9.4 briefly describes the data streaming/generation features of
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.
9.3 Fast General Purpose Input
The Fast General Purpose Input (FGPI) captures data in a variety of modes:
• 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
