9. MASK OPTIONS
The
μ
PD789415,
μ
PD789416, and
μ
PD789417 have the following mask options.
Mask option for P50 to P53
This option is used to specify whether to incorporate a pull-up resistor, as follows:
<1>
To indicate whether a pull-up resistor is to be incorporated, an individual bit is specified, independently of
the other bits.
<2>
The specification of each bit indicates that a pull-up resistor is not to be incorporated.
Mask option for the V
LC0
to V
