8.8 General purpose IOs
The UCB1400 has 10 programmable digital input/output (I/O) pins. These pins can be
independently programmed as input or output using the IOD[9:0] bits in the
IO Direction Register (0x5C). The output data is determined by the content of the
IO[9:0] bits in the IO Data Register (0x5A), while the actual status of these pins can
be read from the same register bits.
The data on the IO[9:0] pins are fed into the interrupt control block, where they can
generate an interrupt on the rising and/or falling edge of these signals.
8.9 Interrupt generation
The UCB1400 contains a programmable interrupt control block, which can generate
an interrupt for a 0-to-1 and/or 1-to-0 transition on one or more of the IO[9:0] pins, the
audio overload detection, the ADC Ready signal, and the TSPX and TSMX signals.
