21.2
21.2.1
While coming out of Power-on Reset or Brown-out
Reset, the device selects its clock source based on:
a)
b)
The selection is as shown in Table 21-2.
TABLE 21-2:
21.2.3
Enabling the LP oscillator is controlled with two
elements:
1.
2.
The LP oscillator is ON (even during Sleep mode) if
LPOSCEN = 1. The LP oscillator is the device clock if:
• COSC<1:0> = 00 (LP selected as main oscillator)
• LPOSCEN = 1

Note 1: OSC2 pin function is determined by the Primary Oscillator mode selection (FPR<3:0>).
FOS<1:0> configuration bits that select one of
four oscillator groups.
AND FPR<3:0> configuration bits that select
one of 13 oscillator choices within the primary

21.2.2
In order to ensure that a crystal oscillator (or ceramic
resonator) has started and stabilized, an oscillator
start-up timer is included. It is a simple 10-bit counter
that counts 1024 T
oscillator clock to the rest of the system. The time-out
period is designated as T
every time the oscillator has to restart (i.e., on POR,
BOR and wake-up from Sleep). The oscillator start-up
timer is applied to the LP Oscillator, XT, XTL and HS
modes (upon wake-up from Sleep, POR and BOR) for
the primary oscillator.
Keeping the LP oscillator ON at all times allows for a
fast switch to the 32 kHz system clock for lower power
operation. Returning to the faster main oscillator will
still require a start-up time.
