Rev. 1.1
Address:
The port option control register controls the pullup options for port A,
port C, and port E pins. It also controls the drive configuration on port D.
PTE20P — Pins PTE[2:0] Pullup Enable
PTDLDD — LED Direct Drive Control
PTDILDD — Infrared LED Drive Control
Reset:
Read:
Write:
This read/write bit controls the pullup option for the PTE2–PTE0 pins,
regardless whether the pins are input or output.
This read/write bit controls the output current capability of
PTD5–PTD2 pins. When set, each port pin has 10mA current sink
limit. An LED can be connected directly between the port pin and V
without the need of a series resistor.
This read/write bit controls the output current capability of PTD1 and
PTD0 pins. When set, each port pin has 25mA current sink capability.
An infrared LED can be connected directly between the port pin and
V
DD
1 = Configure PTE2–PTE0 to have internal pullups
0 = Disconnect PTE2–PTE0 internal pullups
1 = PTD5–PTD2 configured for direct LED drive capability;
0 = PTD5–PTD2 configured as standard open-drain I/O port pins
.
