Overview
1.3.18
The VIU2 is a crossbar master module accepting an ITU656 compatible video input stream on a parallel interface, converting
the pixel data to RGB or YUV format and transferring the video image to internal frame buffer memory or external DRAM if
available.
1.3.19
The BAM is a block of read-only memory that is programmed once by Freescale. The BAM program is executed every time
the MCU is powered-on or reset in normal mode. The BAM supports different modes of booting. They are:
Additionally the BAM:
1.3.20
This device has two eMIOS modules, each with 16 channels supporting a range of 16-bit Input Capture, Output Compare, Pulse
Width Modulation, and Quadrature Decode functions.
