DD
= 2.7 to 5.5 V)
Notes 1.
When P110 to P117 and P120 to P127 do not contain the pull-down resistors (according to the
specification of the mask option), a high-level input leakage current of 150
μ
A (MAX.) flows only during
1.5 clocks after a read instruction has been executed to read out port 11 or 12 (P11 or P12) or port mode
register 11 or 12 (PM11 or PM12). Outside the 1.5 clocks after a read instruction, the current is 3
μ
A
(MAX.).
2.
When P110 to P117 and P120 to P127 do not contain the pull-down resistors (according to the
specification of the mask option), a high-level input leakage current of 90
μ
A (MAX.) flows only during
1.5 clocks after a read instruction has been executed to read out P11, P12, PM11, or PM12. Outside
the 1.5 clocks after a read instruction, the current is 3
μ
A (MAX.).
3.
When P30 to P37 and P70 to P74 do not contain the pull-down resistors (according to the specification
of the mask option), a low-level input leakage current of –150
μ
A (MAX.) flows only during 1.5 clocks
after a read instruction has been executed to read out port 3 or 7 (P3 or P7) or port mode register 3 or
7 (PM3 or PM7). Outside the 1.5 clocks after a read out instruction, the current is –3
μ
A (MAX.).
4.
Current which flows in the built-in pull-up or pull-down resistor is not included.
Remark
Unless otherwise specified, the characteristics of a shared pin are the same as those of a port pin.
