11.3.1 Internal Signal Definitions
The following signals and clocks are used in the functional description and figures of the OSC module.
11.3.1.1 Oscillator Enable Signal (SIMOSCEN)
The SIMOSCEN signal comes from the system integration module (SIM) and disables the XTAL oscillator
circuit, the RC oscillator, or the internal oscillator in stop mode. OSCENINSTOP in the configuration
register can be used to override this signal.
RST, IRQ: Pins have internal pull up device
All port pins have programmable pull up device
PTA[0:5]: Higher current sink and source capability
PTB[0:7]: Not available on 8-pin devices
