SYMBOL
The bits in the write register provide the data of the I/O pin
when programmed as output.
The bits in the read register return the actual state of the
associated I/O pin.
If '1', the associated I/O pin is defined as output.
If ‘0', the associated I/O pin is defined as input.
If ‘1’, the SIBDOUT pin is forced ‘0’ during the second SIB
word.
If '0', the SIBDOUT pin is three-stated during the second SIB
word.
If '1', the rising edge interrupt of the associated I/O pin is
enabled.
If '1', the rising edge interrupt of the adc_ready signal is
enabled.
If '1', the rising edge interrupt of the TSPX signal is enabled.
If '1', the rising edge interrupt of the TSMX signal is enabled.
If '1', the rising edge interrupt of the telecom clip is enabled.
If '1', the rising edge interrupt of the audio clip is enabled.
If '1', the falling edge interrupt of the associated I/O pin is
enabled.
If '1', the falling edge interrupt of the adc_ready signal is
enabled.
If '1', the falling edge interrupt of the TSPX signal is enabled.
If '1', the falling edge interrupt of the TSMX signal is enabled.
If '1', the falling edge interrupt of the telecom clip is enabled.
If '1', the falling edge interrupt of the audio clip is enabled.
A '0' to '1' transition clears the interrupt of the associated I/O
pin.
Returns the actual interrupt status of the associated I/O pin
A '0' to '1' transition clears the interrupt adc_ready signal.
Returns the actual interrupt status of the adc_ready signal.
A '0' to '1' transition clears the interrupt of the TSPX signal.
Returns the actual interrupt status of the TSPX signal.
A '0' to '1' transition clears the interrupt of the TSMX signal.
Returns the actual interrupt status of the TSMX signal.
