Register
Legend:
MAR: Memory address register
IOAR: I/O address register
ETCR: Execute transfer count register
MAR and IOAR specify the source and destination addresses. MAR specifies a 24-bit source or
destination address. IOAR specifies the lower 8 bits of a fixed address. The upper 16 bits are all
1s. MAR and IOAR are not incremented or decremented.
Figure 8.4 illustrates how idle mode operates.
