—: One of the multiplexed pin functions is allocated, but the pin functions in the reset state are
different.
I: Input
O: Output
H: High
L: Low
Z: High impedance
K: Input pins are high-impedance, output pins hold their state.
Notes: 1. When the port high impedance bit (HIZ) in the standby control register (SBYCR) is set
to 1, the output pins become high-impedance.
2. When the pin pull-up control bit (WPU) in the wait state control register (WCR3) is set to
1, the WAIT pin is pulled up, but if set to 0, it is not pulled up.
