8-bit I/O expander with I2C-bus/SPI interface

Functional description
The device interfaces to a host through either I2C-bus or SPI interface (selectable through
I2C/SPI pin), and provides the host with eight programmable GPIO pins.
7.1 Hardware reset, Power-On Reset (POR) and software reset
These three reset methods are identical and will reset the internal registers as indicated in
Table 3 summarizes the state of registers after reset.
Table 4 summarizes the state of hardware pins after reset.
IRQ
12
O
Interrupt (open-drain, active LOW). Interrupt is enabled when
interrupt sources are enabled in the I/O Interrupt Enable register
(IOIntEna). The interrupt condition is the change of state of the
input pins. An external resistor (1 k
for 3.3 V, 1.5 k for 2.5 V)
must be connected between this pin and VDD.
