(2) the blocking of interrupts is marked by the region a-b 1 / b 2 depending on the actual read cycle. b 1 is when only the intflag is read and a stop condition is received (only intflag is read so only this will be cleared). b 2 is when both registers are read and hence cleared and this is terminated by either an acknowledge or stop bit. (3) interrupt events that occur between a and b set their respective ?ags after the mask bits are cleared. which means that in this diagram an interrupt e vent occurred in period a-b, so after a-b the ?ag goes to logic 1. (4) all interrupt mask bits are cleared after the interrupt ?ag and mask bytes are read. (5) software writes to the mask byte and enables the required mask bits. any ?ags currently set will then trigger a hardware int errupt.

(1) when flag is set next interrupts are blocked until read/write intmsk. (2) read intmsk clears flag, intmsk and intx. (3) write intmsk enables intx. fig 6. interrupt line behavior 001aab489 10 ms v cca flag (1) intx read intmsk (2) write intmsk (3) 10 ms < 10 ms < 10 ms read clears intx
