PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type: I = input, O = output, S = supply
VDDF powered: I/O powered by the alternate sup-
ply rail, supplied by VDDF and VSSF.
In/Output level: CT = CMOS 0.3VDD/0.7VDD with
input trigger
Output level: HS = 10mA high sink (on N-buffer
only)
Port and control configuration:
– Input:float = floating, wpu = weak pull-up, int = in-
terrupt
– Output: OD = open drain, T = true open drain, PP
= push-pull, OP = pull-up enabled by option byte.
Refer to “I/O Port Implementation” on page 51 of
the datasheet for more details on the software
configuration of the
I/O ports.
The RESET configuration of each pin is shown in
bold.

SX
Power Line for alternate supply rail. Can be
used as input (with external supply) or output
(when using the on-chip voltage regulator).
Note: An external decoupling capacitor (min.
20nF) must be connected to this pin to stabilize
the regulator.
