ANB0 - 3 — Analog inputs to ADC B, channel 0
ANB4 - 7 — Analog inputs to ADC B, channel 1
Temperature Sense Diode — This signal connects to an
on-chip diode that can be connected to one of the ADC inputs
and used to monitor the temperature of the die. Must be
bypassed with a 0.01μF capacitor.
FlexCAN Receive Data — This is the CAN input. This pin has
an internal pull-up resistor.
To deactivate the internal pull-up resistor, set the CAN bit in
the SIM_PUDR register.
FlexCAN Transmit Data — CAN output with internal pull-up
enable at reset. *
* Note: If a pin is configured as open drain output mode,
internal pull-up will automatically be disabled when it outputs
low. Internal pull-up will be enabled unless it has been
manually disabled by clearing the corresponding bit in the
PUREN register of the GPIO module, when it outputs high.
If a pin is configured as push-pull output mode, internal pull-up
will automatically be disabled, whether it outputs low or high.
TC0 — Timer C, Channel 0 and 1
Port E GPIO — These GPIO pins can be individually
programmed as input or output pins.
At reset, these pins default to Timer functionality.
To deactivate the internal pull-up resistor, clear the appropriate
bit of the GPIOE_PUR register.
