Signal Description
GPIOA10
(CMPAI2)
27
Input/
Output
Input,
internal
pull-up
enabled
Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Input
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.
GPIOA11
(CMPBI2)
6
Input/
Output
Input,
internal
pull-up
enabled
Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Input
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.
GPIOB0
(SCLK0)
32
Input/
Output
Input,
internal
pull-up
enabled
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Input/
Output
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)
Serial Clock — This pin serves as the I2C serial clock.
Input/
Output
After reset, the default state is GPIOB0. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
5The SCL signal is also brought out on the GPIOB7 pin.
GPIOB1
2
Input/
Output
Input,
internal
pull-up
enabled
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
(SS0)
Input/
QSPI0 Slave Select — SS is used in slave mode to indicate to the
Output
QSPI0 module that the current transfer is to be received.
(SDA6)
Serial Data — This pin serves as the I2C serial data line.
Input
After reset, the default state is GPIOB1. The peripheral functionality
is controlled via the SIM. See Section 6.3.16.
6The SDA signal is also brought out on the GPIOB6 pin.
