2:0 | INTCODE | R/W | 0h | Interrupt code. The binary-coded-interrupt vector indicates which interrupt has occurred. Reading the ICIVR clears the interrupt code except ARDY[011] RRDY[100] and XRDY[101]. Interrupt code for ARDY RRDY and XRDY is cleared when ARDY ICRRDY and ICXRDY bits in the ICSTR is cleared to default value respectively. If other interrupts are pending a new interrupt is generated. If there are more than one interrupt flag Reading the ICIVR clears the highest priority interrupt code. Reading the ICIVR also clears corresponding status bit in the ICSTR except ARDY ICRRDY ICXRDY and AAS. Note that users must read [clear] the ICIVR before doing another start otherwise the ICIVR could contain incorrect [old interrupt flags] value. ________________________________________________ Interrupt Code____________Interrupt Occurred__________ _000_[default]_________________None _001_[highest priority]____Arbitration Lost interrupt _010__________________No Acknowledgement interrupt _011__________________Register Access Ready interrupt _100__________________Receive Data Ready interrupt _101__________________Transmit Data Ready interrupt _110__________________Stop Condition Detection _111_[lowest priority]_____Address As Target - [RW] ________________________________________________ |
