Port B GPIO
— This GPIO pin can be individually programmed as
an input or output pin.
Receive Data
— SCI receive data input.
Serial Data
— This pin serves as the I
2
C serial data line.
Clock Input
— This pin serves as an optional external clock input.
After reset, the default state is GPIOB6. The peripheral functionality
is controlled via the SIM (See
Section 6.3.8
) and the CLKMODE bit
of the OCCS Oscillator Control Register.
