PIN DESCRIPTION (Cont’d)

For external pin connection guidelines, refer to See “ELECTRICAL CHARACTERISTICS” on page 162.

Legend / Abbreviations for Table 1:

Type:

I = input, O = output, S = supply

Input level:

A = Dedicated analog input

In/Output level: C = CMOS 0.3VDD/0.7VDD

CT= CMOS 0.3VDD/0.7VDD with input trigger

TT= TTL 0.8V / 2V with Schmitt trigger

Output level: HS = 20mA high sink (on N-buffer only)

Port and control configuration:

– Input:

float = floating, wpu = weak pull-up, int = interrupt 1), ana = analog

– Output:

OD = open drain 2), PP = push-pull

Refer to “I/O PORTS” on page 47 for more details on the software configuration of the I/O ports.

The RESET configuration of each pin is shown in bold. This configuration is valid as long as the device is

in reset state.
