I/O port characteristics
General input/output characteristics
Unless otherwise specified, the parameters given in Table 33 are derived from tests
performed under the conditions summarized in Table 7. All I/Os are CMOS and TTL
compliant.
All unused pins must be configured in either of the three modes below:
●
as outputs with an external pull-up or pull-down resistor and held at a fixed voltage (see
●
as push-pull outputs with 0 written into the data register
●
or as analog inputs
Table 33.
