Oscillator (OSC)
6.4 I/O Signals
The following paragraphs describe the oscillator I/O signals.
6.4.1 Crystal Amplifier Input Pin (OSC1)
OSC1 pin is an input to the crystal oscillator amplifier or the input to the RC oscillator circuit.
6.4.2 Crystal Amplifier Output Pin (OSC2/RCCLK/PTA6/KBI6)
For the XTAL oscillator, OSC2 pin is the output of the crystal oscillator inverting amplifier.
For the RC oscillator, OSC2 pin can be configured as a general purpose I/O pin PTA6, or the output of
the RC oscillator, RCCLK.
6.4.3 Oscillator Enable Signal (SIMOSCEN)
The SIMOSCEN signal comes from the system integration module (SIM) and enables/disables the XTAL
oscillator circuit or the RC-oscillator.
6.4.4 XTAL Oscillator Clock (XTALCLK)
XTALCLK is the XTAL oscillator output signal. It runs at the full speed of the crystal (f
directly from the crystal oscillator circuit.
and OSC2 and may not represent the actual circuitry. The duty cycle of XTALCLK is unknown and may
depend on the crystal and other external factors. Also, the frequency and amplitude of XTALCLK can be
unstable at start-up.
6.4.5 RC Oscillator Clock (RCCLK)
RCCLK is the RC oscillator output signal. Its frequency is directly proportional to the time constant of the
external R and C.
the actual circuitry.
6.4.6 Oscillator Out 2 (2OSCOUT)
2OSCOUT is same as the input clock (XTALCLK or RCCLK). This signal is driven to the SIM module.

The internal oscillator is a free running oscillator and is available after each
POR or reset. It is turned-off in stop mode by setting the STOP_ICLKDIS
bit in CONFIG2 (see
