PIR7

Peripheral Interrupt Request Register 7
Notes:
  1. 1. Interrupt flag bits get set when an interrupt condition occurs, regardless of the state of its corresponding enable bit, or the global enable bit. User software must ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
  2. 2.SPI1IF is a read-only bit. To clear the interrupt condition, all bits in the SPI1INTF register must be cleared.
  3. 3.SPI1TXIF and SPI1RXIF are read-only bits and cannot be set/cleared by software.
  4. 4.I2C1EIF is a read-only bit. To clear the interrupt condition, all bits in the I2C1ERR register must be cleared.
  5. 5.I2C1IF is a read-only bit. To clear the interrupt condition, all bits in the I2C1PIR register must be cleared.
  6. 6.I2C1TXIF and I2C1RXIF are read-only bits. To clear the interrupt condition, the CLRBF bit in I2C1STAT1 must be set.
