Figure 36
The read access timing is illustrated in
name is associated with each read register (EOCR, M4R, M56R). An EOC interrupt
indicates that the value of the EOCR register has been changed and updated. So do the
M4 and M56 interrupts. Note that unlike the 6 ms and 12 ms interrupts the ’read’
interrupts are only generated on change of the register value and do not occur
periodically.
The EOC, M4 and M56 interrupt bits are all accommodated in the ISTAU register.
