If the oscillator module is configured for LP, XT or HS
modes, the Oscillator Start-up Timer (OST) counts
1024 oscillations from OSC1. This occurs following a
Power-on Reset (POR) and when the Power-up Timer
(PWRT) has expired (if configured), or a wake-up from
Sleep. During this time, the program counter does not
increment and program execution is suspended. The
OST ensures that the oscillator circuit, using a quartz
crystal resonator or ceramic resonator, has started and
is providing a stable system clock to the oscillator
module.
In order to minimize latency between external oscillator
start-up and code execution, the Two-Speed Clock
Start-up mode can be selected (see
“Two-Speed Clock Start-up
5.2.1.4
The oscillator module contains a 4xPLL that can be
used with both external and internal clock sources to
provide a system clock source. The input frequency for
the 4xPLL must fall within specifications. See the PLL
Clock
“Electrical Specifications”
The 4xPLL may be enabled for use by one of two
