Bits 15 to 8: Not Used (—)
Bits 7 to 4: Port Interrupt Status Register [4:1] (PISR[4:1] ) The corresponding bit is set when any of the bits in
the port interrupt status registers (PORT.ISR) are set. The INT interrupt pin will be driven low when any bit is set
and the corresponding GL.ISRIE.PISRIE[4:1] interrupt enable bit is enabled.
Bit 1: Transmit System Interface Status Register Interrupt Status (TSSR) This bit is set when any of the
latched status register bits in the transmit system interface are set and enabled for interrupt. The INT pin will be
driven low when this bit is set and the GL.ISRIE.TSSRIE interrupt enable bit is enabled.
Bit 0: Global Status Register Interrupt Status (GSR) This bit is set when any of the latched status register bits in
the global latched status register (GL.SRL) are set and enabled for interrupt. The INT interrupt pin will be driven low
when this bit is set and the GL.ISRIE.GSRIE interrupt enable bit is enabled.
