16.1.2 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) or a low
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
by
EM
Microelectronic Marin SA. Refer
also to chapter 17.2 and 17.3 for
the pull values.
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
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-up
with R1=100 KOhm
