20.2.1
While coming out of Power-on Reset or Brown-out
Reset, the device selects its clock source based on:
• FOS<1:0> Configuration bits, which select one of
• FPR<3:0> Configuration bits, which select one of
Table 20-2
selection.
TABLE 20-2:
20.2.2
To ensure that a crystal oscillator (or ceramic resona-
tor) has started and stabilized, an Oscillator Start-up
Timer is included. It is a simple 10-bit counter that
counts 1024 T
clock to the rest of the system. The time-out period is
designated as T
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.

Enabling the LP oscillator is controlled with two elements:
• The current oscillator group bits COSC<1:0>.
• The LPOSCEN bit (OSCON register).
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
Keeping the LP oscillator on at all times allows for a fast
switch to the 32 kHz system clock for lower power oper-
ation. Returning to the faster main oscillator still
requires a start-up time.
