DTMF

When key is pressed, CDMA Module generates standard DTMF tone and sends it to the local

audio path (speaker). If the Mobile station is in traffic state, the CDMA Module sends DTMF Message to

the Base Station and to the local audio path (speaker) at the same time. The network will deliver the

analog DTMF tone or DTMF Message to its final destination.

This feature is not implemented but can be added, please contact ed@anydata.com

for technical support. .

4.7.2 MultiMediaCard controller

DTEV-Dual contains a MultiMediaCard (MMC) controller that provides a link between the

ARM bus master and the MultiMediaCard bus for storing digital music, games, address books and photos.

The SD card supports a 1-bit SD bi-directional bus mode. SD bus pins are CLK, CMD and DAT in 1-bit

mode and CLK, CMD, and DAT[0:3] in 4-bit mode. The MultiMediaCard also supports the 1-bit bi-

directional MMC bus mode that has CLK, CMD, and DAT bus pins. The CMD and DAT pins are bi-

directional on the SD 1-bit, SD 4-bit, and MMC 1-bit. DTEV-Dual can’t support SD 4-bit mode. MMC

version 3.31 is supported for the ROM class and R/W MMCs. SD Memory Card Physical Layer

Specification Version 1.01 is supported in SD bus mode.
