IO4-OEN
Enabling output driver of the IO4 pin
IO4-OEN = 0 The output driver of the IO4 pin is disabled.
IO4-OEN = 1 The output driver of the IO4 pin is enabled.
IO3-OEN
Enabling output driver of the IO3 pin
IO3-OEN = 0 The output driver of the IO3 pin is disabled.
IO3-OEN = 1 The output driver of the IO3 pin is enabled.
IO2-OEN
Enabling output driver of the IO2 pin.
If SLIC-P is selected (bits SEL-SLIC [1:0] in register BCR1 set to 01), pin
IO2 cannot be controlled by the user but is utilized by the SLICOFI-2 to
control the C3 input of SLIC-P.
IO2-OEN = 0 The output driver of the IO2 pin is disabled.
IO2-OEN = 1 The output driver of the IO2 pin is enabled.
IO1-OEN
Enabling output driver of the IO1 pin.
If external ringing is selected (bit REXT-EN in register BCR2 set to 1), pin
IO1 cannot be controlled by the user but is utilized by the SLICOFI-2 to
control the ring relay.
IO1-OEN = 0 The output driver of the IO1 pin is disabled.
IO1-OEN = 1 The output driver of the IO1 pin is enabled.
IO4-DD
Value for the programmable I/O pin IO4 if programmed as an output pin.
IO4-DD = 0 The corresponding pin is driving a logic 0.
IO4-DD = 1 The corresponding pin is driving a logic 1.
IO3-DD
Value for the programmable I/O pin IO3 if programmed as an output pin.
IO3-DD = 0 The corresponding pin is driving a logic 0.
IO3-DD = 1 The corresponding pin is driving a logic 1.
