Notes 1. Only when selected by a mask option or port function register
2. If there is no on-chip pull-up resistor for P50 to P53 (specified by a mask option) and 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 –60
µ
A flows during only one cycle. At all other times, the maximum
leakage current is –3

Remark Unless otherwise specified, the characteristics of alternate-function pins are the same as those of port
pins.
