I2CI—I2C Interrupt Request
0 = No interrupt request is pending for the I2C.
1 = An interrupt request from the I2C is awaiting service. Writing 1 to this bit Resets it to 0.
SPII—SPI Interrupt Request
0 = No interrupt request is pending for the SPI.
1 = An interrupt request from the SPI is awaiting service. Writing 1 to this bit Resets it to 0.
ADCI—ADC Interrupt Request
0 = No interrupt request is pending for ADC.
1 = An interrupt request from ADC is awaiting service. Writing 1 to this bit Resets it to 0.
The interrupt request 1 (IRQ1) register (see
vectored and polled interrupts. When a request is presented to the interrupt controller, the
corresponding bit in the IRQ1 register becomes 1. If interrupts are globally enabled
(vectored interrupts), the interrupt controller passes an interrupt request to the ZNEO
CPU. If interrupts are globally disabled (polled interrupts), the ZNEO CPU reads the
interrupt request 1 register to determine, if any interrupt requests are pending. Writing 1 to
the bits in this register clears the interrupt. The bits of this register are set by writing 1 to
the interrupt request 1 set regsiter (IRQ1SET) at address FF_E035H.
PADxI—Port A/D Pin x Interrupt Request
0 = No interrupt request is pending for GPIO port A/D pin x.
1 = An interrupt request from GPIO port A/D pin x is awaiting service. Writing 1 to these
bits Resets it to 0.
