Note
If there is no on-chip pull-up resistor for P50 to P53 (specified by the mask option), if P50 to P53 have
been set to input mode when a read instruction is executed to read from P50 to P53, a low-level input
leakage current of up to –30 µA flows during only one cycle. At all other times, the maximum leakage
current is –3 µA.
Remarks 1. Pin names enclosed in parentheses are when using the µPD789314, 789316.
2. Unless specified otherwise, the characteristics of alternate-function pins are the same as those of
port pins.
