20.2 Oscillator Configurations
20.2.1 INITIAL CLOCK SOURCE
SELECTION
While coming out of Power-on Reset or Brown-out
Reset, the device selects its clock source based on:
a) FOS<2:0> Configuration bits that select one of
four oscillator groups, and
b) FPR<4:0> Configuration bits that select the
oscillator choices within the primary group.
The selection is as shown in Table 20-2.

Note 1: OSC2 pin function is determined by FPR<4:0>.
2: OSC1 pin cannot be used as an I/O pin even if the secondary oscillator or an internal clock source is
selected at all times.
