Input
FAULT3 — This fault input pin is used for disabling selected PWM
outputs in cases where fault conditions originate off-chip.
External Clock Input— This pin serves as an external clock input.
After reset, the default state is GPIOB5. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.

(CLKIN)
External Clock Input — This pin serves as an external clock input.
After reset, the default state is GPIOB6. The peripheral functionality
is controlled via the SIM (See Section 6.3.16) and the CLKMODE bit
of the OCCS Oscillator Control Register.
9The SDA signal is also brought out on the GPIOB1 pin.
