If ‘1’, the tspx pin is powered
If ‘1’, the tsmx pin is powered
If ‘1’, the tspy pin is powered
If ‘1’, the tspy pin is powered
If ‘1’, the tspx pin is grounded
If ‘1’, the tsmx pin is grounded
If ‘1’, the tspy pin is grounded
If ‘1’, the tspy pin is grounded
Touch screen operation mode
If ‘1’, the touch screen bias circuitry is activated.
This bit returns the inverted state of the tspx pin,
‘0’ is high voltage (pen up), ‘1’ is low voltage (pen down)
This bit returns the inverted state of the tsmx pin,
‘0’ is high voltage (pen up), ‘1’ is low voltage (pen down)
If ‘1’, the adc sync mode is activated
If ‘1’, the internal reference voltage is connected to the vrefbyp pin.
ADC input selection bits:
If ‘1’, an external reference voltage has to be applied to the vrefbyp pin
A ‘0’ to ‘1’ transition starts the adc conversion sequence.
If ‘1’, the adc circuit is activated
Returns the ADC result
Returns ‘0’ if an adc conversion is in progress.
Returns ‘1’ if the 0 adc conversion is completed and the adc data is stored in the
adc_data[9:0] register.
Returns 000011 for all the UCB1100 circuits meeting this specification.
Returns 000000 for all the UCB1100 circuits meeting this specification.
Returns 0001 for all the UCB1100 circuits meeting this specification.
