Oscillator Module (OSC)
11.3.5 RC Oscillator
The RC oscillator circuit is designed for use with an external resistor (R
a tolerance within 25% of the expected frequency. See
The capacitor (C) for the RC oscillator is internal to the MCU. The R
1% or less to minimize its effect on the frequency.
In this configuration, the OSC2 pin can be used as general-purpose input/output (I/O) port pins or other
alternative pin function. The OSC2EN bit can be set to enable the OSC2 output function on the pin.
Enabling the OSC2 output can affect the external RC oscillator frequency, f
11.4 Interrupts
There are no interrupts associated with the OSC module.
11.5 Low-Power Modes
The WAIT and STOP instructions put the MCU in low power-consumption standby modes.
11.5.1 Wait Mode
The OSC module remains active in wait mode.
11.5.2 Stop Mode
The OSC module can be configured to remain active in stop mode by setting OSCENINSTOP located in
a configuration register.
