19. Mask Options
Most options which in many μControllers are realized as metal mask options are directly user selectable with
the option registers, therefore allowing a maximum freedom of choice .
The following options can be selected at the time of programming the metal mask ROM.
19.1 Input / Output Ports
19.1.1 Port A Metal Options
Pull-up or no pull-up can be selected
for each port A input. A pull-up
selection is excluding a pull-down on
the same input.
Pull-down (default) or no pull-down
can be selected for each port A input.
A pull-down selection is excluding a
pull-up on the same 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 by EM Microelectronic Marin
SA.
