application shown in Figs 27 and 28. This feature is
activated by setting bits T[2:0] = 011 after Power-on reset.
This feature is disabled when the same bits are set again.
When ALBC is activated, the output ports BS1, BS2
and BS3 are not programmed by the corresponding
BS bits, but are set according to Tables 10 and 11. When
ALBC is active, bit ALBC = 1. Table 11 summarizes the
programming of the band selection and the charge pump
current when ALBC is active.
