I/O PORTS (Cont’d)
Table 11. Port Configuration
Notes:
1. ST72T311N only
2. For OTP/EPROM version, when OR=0: floating & when OR=1: reserved
3. For OTP/EPROM version, when OR=0: open-drain, high sink capability & when OR=1: reserved
* Reset state (The bits corresponding to unavailable pins are forced to 1 by hardware, this affects the reset status value).
Warning: All bits of the DDR register which correspond to unconnected I/Os must be left at their reset val-
ue. They must not be modified by the user otherwise a spurious interrupt may be generated.
