3.3V Single Supply Mode
Figure 6-1 on page 47
I/O lines and analog blocks will be powered by the same power (VDDIN_5 = VDDIO1 = VDDIO2
= VDDIO3 = VDDANA).
Figure 6-1.
In 3.3V single supply mode, the VDDIN_5 and VDDIN_33 pins should be connected together
externally. The 1.8V internal regulator is connected to the 3.3 V source (VDDIN_5 pin) and its
output feeds VDDCORE.
The 3.3V regulator should be disabled once the circuit is running through the VREG33CTL field
of the VREGCTRL SCIF register.
Figure 6-2 on page 48
I/O lines and analog blocks will be powered by the same power (VDDIN_5 = VDDIN_33 =
VDDIO1 = VDDIO2 = VDDIO3 = VDDANA).
