1.0 Functional Description (Continued)
1.3.1 POWERDOWN OPERATION
Bits F[2] and F[18] provide programmable powerdown modes when the CE pin is HIGH. When CE is LOW, the part is always im-
mediately disabled regardless of powerdown bit status. Refer to
Table 3.
Synchronous and asynchronous powerdown modes are both available by MICROWIRE selection. Synchronous powerdown oc-
curs if the F[18] bit (Powerdown Mode) is HIGH when F[2] bit (Powerdown) becomes HIGH. Asynchronous powerdown occurs
if the F[18] bit is LOW when its F[2] bit becomes HIGH.
In the synchronous powerdown mode (F[18] = HIGH), the powerdown function is gated by the charge pump to prevent unwanted
frequency jumps. Once the powerdown program bit F[2] is loaded, the part will go into powerdown mode after the first successive
charge pump event.
In the asynchronous powerdown mode (F[18] = LOW), the device powers down immediately after latching LOW data into bit F[2].
The device returns to an actively powered up condition in either synchronous or asynchronous mode immediately upon LE latch-
ing LOW data into bit F[2].
Activation of a powerdown condition in either synchronous or asynchronous mode including CE pin activated powerdown has the
following effects:
Removes all active DC current paths.
Forces the R, N, and timeout counters to their load state
conditions.
Will TRI-STATE the charge pump.
Resets the digital lock detect circuitry.
Debiases the f
IN input to a high impedance state.
Disables the oscillator input buffer circuitry.
The MICROWIRE control register remains active and ca-
pable of loading the data.
