PLL FUNCTIONAL DESCRIPTION
The device is controlled via the I2C-bus or the 3-wire bus,
depending on the voltage applied on the SW input.
A HIGH-level on the SW input enables the 3-wire bus;
CE/AS, DA and CL inputs are used as enable (CE), data
and clock inputs respectively. A LOW-level on SW input
enables the I2C-bus; the CE/AS, DA and CL inputs are
used as address selection (AS), SDA and SCL input
respectively (see Table 2).
