I/O Heartbeat Cycle
The Z380 MPU is capable of generating an I/O heartbeat cycle on the I/O bus in response
to an I/O write to an on-chip control register. This cycle is most useful with Z80 family
peripherals, where some members require a transaction that looks like a Z80 CPU instruc-
tion fetch to perform certain interrupt functions (Figure 29).
