Reset
6.2.1 Power-on reset (POR)
When power is initially applied to the MCU or when the supply voltage drops below the
power-on reset re-arm voltage level (V
condition.
As the supply voltage rises, the LVD circuit holds the MCU in reset until the supply has
risen above the LVD low threshold (V
are set following a POR.
6.2.2 System resets
Resetting the MCU provides a way to start processing from a known set of initial
conditions. System reset begins with the on-chip regulator in full regulation and system
clocking generation from an internal reference. When the processor exits reset, it
performs the following:
The on-chip peripheral modules are disabled and the non-analog I/O pins are initially
configured as disabled. The pins with analog functions assigned to them default to their
analog function after reset.
During and following a reset, the JTAG pins have their associated input pins configured
as:
and associated output pin configured as:
Note that the nTRST signal is initially configured as disabled, however once configured
to its JTAG functionality its associated input pin is configured as:
