2 Signal Descriptions
2.1 Pin Characteristics
Table 2
shows MCU pins and their characteristics. All inputs detect CMOS logic levels. All inputs can
be put in a high-impedance state, but the method of doing this differs depending upon pin function. Re-
fer to
Table 4
for a description of output drivers. An entry in the discrete I/O column of
that a pin has an alternate I/O function. The port designation is given when it applies. Refer to
1
for information about port organization.
