PIN DESCRIPTION (Cont’d)
Legend / Abbreviations for Table 1:
Type:
In/Output level: C= CMOS 0.15V
Output level:
Port and control configuration:
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, “ei
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.
