1.2
This section provides details of the functional
characteristics of the VoiceDSP processor. It is di-
vided into the following sections:
• Resetting
• Clocking
• Power-Down Mode
• Power and Grounding
• Memory Interface
• Codec Interface
1.2.1
The RESET pin is used to reset the VoiceDSP pro-
cessor.
On application of power, RESET must be held low
for at least t
that all on-chip voltages are completely stable
before operation. Whenever RESET is applied, it
must also remain active for not less than t
Table 1-10 and Table 1-11. During this period,
and for 100 ms after, the TST signal must be high.
This can be done with a pull-up resistor on the TST
pin.
The value of MWRDY is undefined during the re-
set period, and for 100 ms after. The microcon-
troller should either wait before polling the signal
for the first time, or the signal should be pulled
high during this period.
Upon reset, the ENV0 signal is sampled to deter-
mine the operating environment. During reset,
the EMCS/ENV0 pin is used for the ENV0 input sig-
nals. An internal pull-up resistor sets ENV0 to 1.
After reset, the same pin is used for EMCS.
System Load on ENV0
For any load on the ENV0 pin, the voltage should
not drop below V
Table 1-11).

If the load on the ENV0 pin causes the current to
exceed 10 µA, use an external pull-up resistor to
keep the pin at 1.
Figure 1-2 shows a recommended circuit for
generating a reset signal when the power is
turned on.

1.2.2
The VoiceDSP processor provides an internal os-
cillator that interacts with an external clock
source through the X1 and X2/CLKIN pins. Either
an external single-phase clock signal, or a crystal
oscillator, may be used as the clock source.
External Single-Phase Clock Signal
If an external single-phase clock source is used, it
should be connected to the CLKIN signal as
shown in Figure 1-3, and should conform to the
voltage-level requirements for CLKIN stated in
“ELECTRICAL CHARACTERISTICS” on page 1-18.
