Notes 1.
For P110 to P117 and P120 to P127, a high-level input leak current of 150
m
A (MAX.) flows only during
the 1.5 clocks after an instruction has been executed to read out ports 11, 12 (P11, 12) or port mode
registers 11, 12 (PM11, 12). Outside the period of 1.5 clocks following executing a read-out instruction,
the current is 3
m
A (MAX.).
2.
For P110 to P117 and P120 to P127, a high-level input leak current of 90
m
A (MAX.) flows only during the
1.5 clocks after an instruction has been executed to read out P11, P12, PM11, and PM12. Outside the
period of 1.5 clocks following executing a read-out instruction, the current is 3
m
A (MAX.).
Remark
Unless otherwise specified, the characteristics of a shared pin are the same as those of a port pin.
