power dormant state through software control. Here is a brief list of power-down features. Refer to the
ADSP-2100 Family User’s Manual
, “System Interface” chapter, for detailed information about the
power-down feature.

Table 1 Interrupt Priority & Interrupt Vector Addresses
When the modem pool is reset, interrupt servicing is disabled.
LOW POWER OPERATION
The ADSP-21mod970 has three low power modes that significantly reduce the power dissipation when
the device operates under standby conditions. These modes are:
The CLKOUT pin may also be disabled to reduce external power dissipation.
Power Down
Idle
Slow Idle
Power Down
The ADSP-21mod970 modem pool has a low power feature that lets the modem pool enter a very low
Quick recovery from power down. The modem pool begins executing instructions in as
few as 400 CLKIN cycles.
Support for an externally generated TTL or CMOS processor clock. The external clock
can continue running during power down without affecting the lowest power rating and
400 CLKIN cycle recovery.
Power down is initiated by the software power-down force bit.Interrupt support allows an
unlimited number of instructions to be executed before optionally powering down. The
power down interrupt also can be used as a non-maskable, edge sensitive interrupt.
Context clear/save control allows the modem pool to continue where it left off or start
with a clean context when leaving the power down state.
The RESET pin also can be used to terminate power down.
