Input
Input,
internal
pull-up
enabled
Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Comparator A, Input 2 — This is an analog input to Comparator A.
After reset, the default state is GPIOA10. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.

Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Comparator B, Input 2 — This is an analog input to Comparator B.
After reset, the default state is GPIOA11. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.

Input,
internal
pull-up
enabled
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
QSPI0 Serial Clock — In the master mode, this pin serves as an
output, clocking slaved listeners. In slave mode, this pin serves as
the data clock input. A Schmitt trigger input is used for noise
immunity.
(SCL⁵)
Input/
Output
Serial Clock — This pin serves as the I²C serial clock.
After reset, the default state is GPIOB0. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
5_{The SCL signal is also brought out on the GPIOB7 pin.}

Input,
internal
pull-up
enabled
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
QSPI0 Slave Select — SS is used in slave mode to indicate to the
QSPI0 module that the current transfer is to be received.
(SDA⁶)
Input
Serial Data — This pin serves as the I²C serial data line.
After reset, the default state is GPIOB1. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
6_{The SDA signal is also brought out on the GPIOB6 pin.}
