5.3. Low Power Modes
The Si2400 has three low power modes. These are
described below:
DSP Powerdown. The DSP processor can be
powered down by setting register
SEB[3] (PDDE) = 1b.
In this mode, the serial interface still functions and
the modem will detect ringing and intrusion.
However, no modem modes or tone detection
features will function.
Wake-Up-On-Ring. By issuing the ATz command,
the Si2400 goes into a low power mode where both
the microcontroller and DSP are powered down.
Only an incoming ring or a total reset will power up
the chip again. Return from wake-on-ring will trigger
the ALERT pin if S62[4] (WOR) = 1b (WOR = 0b by
default).
Total Powerdown. Setting SF1[5] = 1b and
SF1[6] = 1b will place the Si2400 into a total
powerdown mode. All logic is powered down,
including the crystal oscillator and clock-out pin.
Only a hardware reset can restart the Si2400.
5.4. Global DAA Operation
The Si2400 chipset contains an integrated silicon direct
access arrangement (silicon DAA) that provides a
programmable line interface to meet international
telephone line requirements. Table 13 gives the DAA
register settings required to meet various country PTT
standards. A detailed description of the registers in

Note:
1. See "DC Termination" on page 79 for more information.
2. The following countries require the same settings as Brazil: Armenia, China, Egypt, Georgia, Japan, Jordan,
Kazakhstan, Kyrgyzstan, Malaysia, Muldova, Oman, Pakistan, Qatar, Russia, Syria, Taiwan, Thailand, Ukraine.
3. The following countries require the same settings as CTR21: Austria, Bahrain, Belgium, Bulgaria, Croatia, Cyprus,
