Input/output for P1.0 to P1.4. Input for P1.5.

P2.2

Port 2: Port 2 is a single bit I/O port with a user-conﬁgurable output type.

During reset Port 2 latches are conﬁgured in the input only mode with the

internal pull-up disabled. The operation of this Port 2 pin as an input and

output depends upon the port conﬁguration selected. Refer to Section

8.13.1 “Port conﬁgurations” and Table 15 “Static characteristics” for

details.

This pin has a Schmitt triggered input.

VSS

Ground: 0 V reference.

VDD

Power supply: This is the power supply voltage for normal operation as

well as Idle and Power-down modes.
