Multiple hardware interrupt functionality on near-field communication (NFC)

摘要: Hardware interrupt functionality associated with a disable pin may be used to place near-field communication (NFC) device into various operational modes. For example, intermediate voltage windows defined within an I/O domain and resistive divider running off rail generate multiple reference voltages the domain. In one embodiment, different comparators compare on generated determine whether falls of windows. As such, if particular comparator determines that windows, control signal transition NFC corresponding mode.
