Preliminary
2.2 Signal Pins
After reset, each pin is configured for its primary function (listed first). In the 56F8123, after reset, each
pin must be configured for the desired function. The initialization software will configure each pin for the
function listed first for each pin, as shown in Table 2-2. Any alternate functionality must be programmed.
Note: Signals in italics are not available in the 56F8123 device.
If the “State During Reset” lists more than one state for a pin, the first state is the actual reset state. Other
states show the reset condition of the alternate function, which you get if the alternate pin function is
selected without changing the configuration of the alternate peripheral. For example, the SCLK0/GPIOB3
pin shows that it is tri-stated during reset. If the GPIOB_PER is changed to select the GPIO function of
the pin, it will become an input if no other registers are changed.

Supply
I/O Power — This pin supplies 3.3V power to the chip I/O interface
and also the Processor core throught the on-chip voltage regulator, if
it is enabled.

Supply
Oscillator and PLL Power — This pin supplies 3.3V power to the
OSC and to the internal regulator that in turn supplies the Phase
Locked Loop. It must be connected to a clean analog power supply.
VDDA_ADC
41
Supply
ADC Power — This pin supplies 3.3V power to the ADC modules. It
must be connected to a clean analog power supply.
