PIN DESCRIPTION (Cont’d)
For external pin connection guidelines, refer to See “ELECTRICAL CHARACTERISTICS” on page 142.
Legend / Abbreviations for Table 2 and Table 3:
Type:
I = input, O = output, S = supply
Input level:
A = Dedicated analog input
In/Output level: C = CMOS 0.3V_DD/0.7V_DD
C_T= CMOS 0.3V_DD/0.7V_DD with input 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 50 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.
