UCB1200
INTERRUPT CIRCUIT
The UCB1200 contains a programmable interrupt control block, which can generate an interrupt for a '0' to '1' and/or a
'1' to '0' transition on one or more of the IO0-IO9 pins, the audio and telecom clip detect, the adc_ready signal and the
TSPX and TSMX signals.
The interrupt generation mode is set by IO_RIS_INT[n] in register 2 and INT_FAL_ENA[n] in control register 3. The actual
interrupt status of each signal can be read from the control register 4. The interrupt status is cleared whenever a ‘0’ to ‘1’
transition is written in control register 4 for the corresponding bit.
The IRQOUT pin presents the 'OR' function of all interrupt status bits and can be used to give an interrupt to the system
controller.
The interrupt controller is implemented asynchronously. This provides the possibility to generate interrupts when the
SIBCLK is stopped, e.g. an interrupt can be generated in power down mode, when the touch screen is pressed or when
the state of one of the IO pins changes.
