Fractional-N PLL based transmitter
To additionally reduce the total current consumption the power supply of the crystal
oscillator can be switched from V
DDA
to the regulated supply voltage V
REG
by setting the
control bit ENXR in the special function register TXCON.
Table 6.
ENXR

If ENXR is set, the oscillator supply is automatically changed to a regulated supply when
the transmit-state is entered. The XTAL supply is switched back to the unregulated supply
when the transmit-state is exited.
In Power-down mode both gain stages are switched off and XTAL2 is defined by an
internal pull-up resistor R
pu(int)
.

For control of the output power and the modulation characteristics some special function
register bits (ACON, PAM, CASC) are available.
