Input
ANB0 - 3 — Analog inputs to ADC B, channel 0
ANB4 - 7 — Analog inputs to ADC B, channel 1
Temperature Sensor 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
Port E GPIO — This GPIO pin can be programmed as an input or
output pin.
At reset, this pin defaults to timer functionality.
To deactivate the internal pull-up resistor, clear bit 8 of the
GPIOE_PUR register.
