System pins

Note:

None of system pins (except RESET) provides an open drain output.

2.4

Pin muxing

Table 7 defines the pin list and muxing for this device.

Each entry of Table 7 shows all the possible configurations for each pin, via the alternate

functions. The default function assigned to each pin after reset is indicated by ALT0.

Note:

Pins labeled “NC” are to be left unconnected. Any connection to an external circuit or

voltage may cause unpredictable device behavior or damage.

Note:

Pins labeled “Reserved” are to be tied to ground. Not doing so may cause unpredictable

device behavior.

Reset pin

RESET

Bidirectional reset with Schmitt-Trigger characteristics and noise

filter. This pin has medium drive strength. Output drive is open drain

and must be terminated by an external resistor of value 1KOhm.(6)

Bidirectional

Test pin

VPP TEST

Pin for testing purpose only. To be tied to ground in normal

operating mode.

This pad is configured for Fast (F) pad speed.

This pad contains a weak pull-up.

EXTAL is an "Output" in "crystal" mode, and is an "Input" in "ext clock" mode.

In XOSC Bypass Mode, the analog portion of crystal oscillator (amplifier) is disabled. An external clock can be applied at

EXTAL as an input. In XOSC Normal Mode, EXTAL is an output

This pad contains a weak pull-down.

RESET output shall be considered valid only after the 3.3V supply reaches its stable value.
