Figure 3. ADSP-217x Basic System Configuration
Because the ADSP-217x includes an on-chip oscillator circuit,
an external crystal may be used. The crystal should be con-
nected across the CLKIN and XTAL pins, with two capacitors
connected as shown in Figure 4. A parallel-resonant, fundamen-
tal frequency, microprocessor-grade crystal should be used.

Figure 4. External Crystal Connections
A clock output (CLKOUT) signal is generated by the processor
at the processor’s cycle rate. This can be enabled and disabled
by the CLKODIS bit in the SPORT0 Autobuffer Control Reg-
ister, DM[0x3FF3].
Reset
The RESET signal initiates a master reset of the ADSP-217x.
The RESET signal must be asserted during the power-up se-
quence to assure proper initialization. RESET during initial
power-up must be held long enough to allow the internal clock

to stabilize. If RESET is activated any time after power-up, the
clock continues to run and does not require stabilization time.
The power-up sequence is defined as the total time required for
the crystal oscillator circuit to stabilize after a valid VDD is ap-
plied to the processor, and for the internal phase-locked loop
(PLL) to lock onto the specific crystal frequency. A minimum of
2000 CLKIN cycles ensures that the PLL has locked but does
not include the crystal oscillator start-up time. During this
power-up sequence the RESET signal should be held low. On
any subsequent resets, the RESET signal must meet the mini-
mum pulse width specification, tRSP.
The RESET input contains some hysteresis; however, if you use
an RC circuit to generate your RESET signal, the use of an ex-
ternal Schmidt trigger is recommended.
The master reset sets all internal stack pointers to the empty
stack condition, masks all interrupts and clears the MSTAT reg-
ister. When RESET is released, if there is no pending bus re-
quest and the chip is configured for booting (MMAP = 0), the
boot-loading sequence is performed. Then the first instruction is
fetched from internal program memory location 0x0000.
