The bits in the write register provide the data of the io pin when programmed as output.
The bits in the read register return the actual state of the associated io pin.
If ‘1’, the associated io pin is defined as output.
If ‘0’, the associated io pin is defined as input
If ‘1’, the sibdout pin is forced ‘0’ during the second sib word.
If ‘0’, the sibdout pin tristated during the second sib word
If ‘1’, the rising edge interrupt of the associated io 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 io 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 associate io pin
Returns the actual interrupt status of the associated io 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
A ‘0’ to ‘1’ transition clears the interrupt of the telecom clip
Returns the actual interrupt status of the telecom clip
A ‘0’ to ‘1’ transition clears the interrupt of the audio clip
Returns the actual interrupt status of the audio clip
