PIN DESCRIPTION (Cont’d)
For more details, refer to “ELECTRICAL CHARACTERISTICS” on page 110
Legend / Abbreviations for Table 1:
Type: I = input, O = output, S = supply
In/Output level: C = CMOS
C
T
= CMOS with input trigger
Output level: HS = high sink (on N-buffer only)
Port and control configuration:
– Input: float = floating, wpu = weak pull-up, int = interrupt
1)
, ana = analog ports
– Output: OD = open drain
2)
, PP = push-pull
Refer to “I/O PORTS” on page 39 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.
