19.1.2 Port B Metal Options
Pull-up or no pull-up can be
selected for each port B input. The
pull-up is only active in Nch. open
drain mode.
Pull-down or no pull-down can be
selected for each port B input.
The total pull value (pull-up or pull-
down) is a series resistance out of
the resistance R1 and the switching
transistor. As a switching transistor
the user can choose between a high
impedance
(weak)
impedance (strong) switch. Weak ,
strong or none must be chosen.
The default is strong. The default
resistor R1 value is 100 KOhm. The
user may choose a different value
from 150 KOhm down to 0 Ohm.
However the value must first be
checked
and
agreed

To select an option put an
X
in
column 1,2 and 4 and reconfirm the
R1 value in column 3.
The default value is : Strong pull-
down with R1=100 KOhm
