12 MEDIAPLUG
The S1D13806 is designed with support for MediaPlug. MediaPlug is a digital interface supporting
the Winnov Videum camera. The Videum camera supports simultaneous video and audio capture of
streaming (real-time) and still images. It also supports streaming live video at speeds near 30 frames
per second on fast host systems (i.e. Pentium-2 300MHz or faster).
12.1 Programming
MediaPlug and the Winnov Videum camera are a proprietary design of Winnov. Due to the com-
plexity of the digital interface, all software and drivers for the camera are provided by Winnov. Cus-
tomers intending to use the MediaPlug interface in their design should contact Epson Electronics
America to obtain the latest S1D13806 MediaPlug drivers for testing purposes.
The MediaPlug interface on the S1D13806 must be enabled to function correctly. To enable the
MediaPlug interface, CONF7 must be high (1) on the rising edge of RESET#. When the MediaPlug
interface is enabled, GPIO12 is controlled by the MediaPlug LCMD register, and the GPIO12
bits in both REG[005h] and REG[009h] have no effect. Also when the MediaPlug interface is
enabled, the camera power (VMPEPWR) is controlled by GPIO12 pin.
The MediaPlug LCMD 16-bit register REG[1000h] contains status bits which can be read by soft-
ware. For further information on these status bits, see the “S1D13806 Hardware Functional Specifi-
cation,” document number X28B-A-001-xx.
The MediaPlug IC Revision bits (REG[1000h] bits 11-8) contain the revision of the interface. The
16-bit value read from REG[1000h] should be masked with 0F00h and compared with 0300h (the
current revision of the interface).
The MediaPlug Cable Detected Status bit (REG[1000h] bit 7) determines if a camera is connected to
the MediaPlug interface. When this bit returns a 0, a camera is connected. When this bit returns a 1,
a camera is not connected.
The MediaPlug Power Enable to Remote bit (REG[1000h], bit 1) controls the power to the remote
camera. GPIO12 is controlled by this bit when the MediaPlug interface is enabled. Writing this bit is
necessary only when software needs to control the GPIO12 pin.
