■PIN DESCRIPTIONS
Symbol meanings
Assigned signal: The signal listed at the top of each pin is assigned in the initial state. The pin function must be
switched via software to assign another signal (see the “I/O Ports” chapter).
I/O: I = Input
O = Output
I/O = Input/output
P = Power supply
A = Analog signal
Hi-Z = High impedance state
Initial state: I (Pull-up) = Input with pulled up
I (Pull-down) = Input with pulled down
Hi-Z = High impedance state
O (H) = High level output
O (L) = Low level output
Tolerant fail-safe structure:
✓= Over voltage tolerant fail-safe type I/O cell included (see the “I/O Ports” chapter)
The over voltage tolerant fail-safe type I/O cell allows interfacing without passing un-
necessary current even if a voltage exceeding VDD is applied to the port. Also unneces-
sary current is not consumed when the port is externally biased without supplying VDD.
