20.2
20.2.1
While coming out of Power-on Reset or Brown-out
Reset, the device selects its clock source based on:
a)
b)
Table 20-2 shows the Configuration bit values for clock
selection.
TABLE 20-2:
20.2.2
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

Oscillator Configurations
OSC2 pin is either usable as general-purpose I/O or is not usable, depending on the Primary Oscillator
mode selection (FPR<3:0>).
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.

20.2.3
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)
