PIN DESCRIPTION (Cont’d)
For external pin connection guidelines, refer to See “ELECTRICAL CHARACTERISTICS” on page 138.
Legend / Abbreviations for Table 2 :
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 46 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.
