4.3. Low Power Modes
The Si2401 has three low-power modes:
DSP Powerdown. The DSP processor can be
powered down by setting register
SEB[3] (PDDE) = 1.
In this mode, the serial interface still functions, and
the modem detects ringing and intrusion. However,
no modem modes or tone detection features
function.
Wake-Up-On-Ring. By issuing the ATz command,
the Si2401 goes into a low-power mode where both
the microcontroller and DSP are powered down.
Only an incoming ring, a low TXD signal, or a total
reset will power up the chip again. Return from
wake-on-ring triggers the INT pin if S09[6]
(WOR) = 1 (WOR = 0b by default).
Total Powerdown. Setting SF1[5] = 1 and SF1[6] = 1
places the Si2401 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 Si2401.
4.4. Global DAA Operation
The Si2401 chipset contains an integrated silicon direct
access arrangement (silicon DAA) that provides a
programmable line interface to meet international
telephone line requirements. Table 10 gives the DAA
register settings required to meet various country PTT
standards.
