Product data sheet Rev. 3 — 18 September 2013 12 of 49 NXP Semiconductors PCAL6408A Low-voltage translating, 8-bit I2C-bus/SMBus I/O expander 7.4.10 Interrupt status register (46h) This read-only register is used to identify the source of an interrupt. When read, a logic 1 indicates that the corresponding input pin was the source of the interrupt. A logic 0 indicates that the input pin is not the source of an interrupt. When a corresponding bit in the interrupt mask register is set to 1 (masked), the interrupt status bit returns logic 0. 7.4.11 Output port configuration register (4Fh) The output port configuration register selects port-wise push-pull or open-drain I/O stage. A logic 0 configures the I/O as push-pull (Q1 and Q2 are active, see Figure 9). A logic 1 configures the I/O as open-drain (Q1 is disabled, Q2 is active) and the recommended command sequence is to program this register (4Fh) before the Configuration register (03h) sets the port pins as outputs.
