PIN DESCRIPTION (Cont’d)
Legend / Abbreviations for Table 1:
Type:
I = input, O = output, S = supply
In/Output level: C= CMOS 0.15VDD/0.85VDD with input trigger
CT= CMOS 0.3VDD/0.7VDD 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 See “I/O PORTS” on page 37. for more details on the software configuration of the I/O ports.
The RESET configuration of each pin is shown in bold which is valid as long as the device is in reset state.
Table 1. Device Pin Description
Note:
In the interrupt input column, “eix” defines the associated external interrupt vector. If the weak pull-up col-
umn (wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input,
else the configuration is floating interrupt input.
