enabled
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
TA1 — Timer A, Channel 1
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.

Receive Data 0 — QSCI0 receive data input.
Serial Data — This pin serves as the I
2
C serial data line.
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.

2
C serial clock.
After reset, the default state is GPIOB7. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
