Bit 4: Port Interrupt Status Register (PISR) This 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 this bit is set and the GL.ISRIE.PISRIE
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.

Bit 4: Port Interrupt Status Register Interrupt Enable (PISRIE) When this is enabled and the
status bit is set, the INT pin will be driven low.
Bit 0: Global Status Register Interrupt Status Interrupt Enable (GSRIE) When this interrupt enable bit is
enabled, and the GL.ISR.GSR status bit is set, the INT pin will be driven low.
