13.10 Scanner Interrupt
The scanner will trigger an interrupt when the SCANGO bit
      transitions from ‘1’ to ‘0’. The SCANIF interrupt flag of one of the PIR registers is
      set when the last memory location is reached and the data are entered into the CRCDATA
      registers. The SCANIF bit must be cleared by software. The SCAN interrupt enable is the SCANIE
      bit of the corresponding PIE register.
