PO: Power pin
3T: 3 V tolerant pin (voltage max. respect to Vss is -0.5 to VDD + 0.5)
5V: 5 V tolerant pin (voltage max. respect to Vss is -0.5 to 5.5 only if chip is powered)
5S: 5 V tolerant and fail-safe pin (-0.5-5.5 max. voltage w.r.t. Vss even if chip is not pow-
ered).

Table 1 Pin definitions
Port 2 is a 4-bit bidirectional I/O port. It is bit-wise programma-
ble for input or output via direction bits. For a pin configured as
input, the output driver is put into high-impedance state. Port 2
outputs can be configured as push/pull or open drain drivers.
The following Port 2 pins have alternate functions:

P2.11
Port 7 is a 4-bit bidirectional I/O port. It is bit-wise programma-
ble for input or output via direction bits. For a pin configured as
input, the output driver is put into high-impedance state. Port
7outputs can be configured as push/pull or open drain drivers.
The following Port 7 pins have alternate functions:
P7.3
Input timing pin for the return from powerdown circuit and
power-up asynchronous reset.
Digital supply voltage.
Digital ground.
