are brought off-chip so that they can be bypassed. Connect to a
0.1μF ceramic low ESR capacitor
connected to a low-noise V
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.
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
In the 56F8323, the default state after reset is CAN_RX.
In the 56F8123, the default state is not one of the functions offered
and must be reconfigured.
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.
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
In the 56F8323, the default state after reset is CAN_TX.
In the 56F8123, the default state is not one of the functions offered
and must be reconfigured.
