Regulated core power supply (internal use only, no external current loading)

27 I/O Input terminal for crystal oscillator

28 I/O Output terminal for crystal oscillator

Auxiliary power supply AUXVCC3 for back up subsystem

30 I External time capture pin 1 for RTC_C

31 I External time capture pin 0 for RTC_C

General-purpose digital I/O with port interrupt

32 I/O SMCLK clock output

Comparator_B input CB0

Analog input A5 - 10-bit ADC

General-purpose digital I/O with port interrupt

33 I/O MCLK clock output

Comparator_B input CB1

Analog input A4 - 10-bit ADC

(1) I = input, O = output

(2) It is recommended to short unused analog input pairs and connect them to analog ground.

(3) The pins VDSYS1 and VDSYS2 must be connected externally on board for proper device operation.

(4) VCORE is for internal use only. No external current loading is possible. VCORE should only be connected to the recommended

capacitor value, CVCORE.
