Function as described above
Function as described above.
The charge pump current can be programmed by bits C1 & C0 within
data byte 4, as defined in Figure 29.
The device power and hence signal handling can be programmed by
bits I2 - I0 within data byte 5, as defined in Figure 7.
In all power settings the synthesizer remains enabled to facilitate rapid
PLL lock reacquisition
The test modes are defined by bits T2 - T0 as described in Figure 26.
The general purpose port can be programmed by bits P0;
Logic '1' = on
Logic '0' = off (high impedance) - this is the default state at device power
on
BUFREF output by bit RE as described in Figure 27. The BUFREF
output defaults to the 'ON' condition at device power up. This output is
only available on the SSOP package.
