PIC32MX FAMILY
10.3.1
When the primary oscillator (POSC) on OSCI and
OSCO is not configured as a clock source the OSCI pin
is automatically reconfigured as a digital I/O. In this
configuration, as well as when the primary oscillator is
configured for EC mode (POSCMD1:POSCMD0 = 00),
the OSCO pin can also be configured as a digital I/O by
programming the OSCIOFCN Configuration bit.
When OSCIOFCN is unprogrammed (‘1’), a PBCLK is
available on OSCO for testing or synchronization pur-
poses. With OSCIOFCN programmed (‘0’), the OSCO
pin becomes a general purpose I/O pin. In both of these
configurations, the feedback device between OSCI and
OSCO is turned off to save current.
10.3.2
When the secondary oscillator (SOSC) on SOSCI and
SOSCO pin is not configured as a clock source the pins
are automatically reconfigured as a digital I/O.
