Dynamic RAM Refresh Control
The Z8X180 incorporates a dynamic RAM refresh control circuit
including 8-bit refresh address generation and programmable refresh
timing. This circuit generates asynchronous refresh cycles inserted at the
programmable interval independent of CPU program execution. For
systems which do not use dynamic RAM, the refresh function can be
disabled.
When the internal refresh controller determines that a refresh cycle should
occur, the current instruction is interrupted at the first breakpoint between
machine cycles. The refresh cycle is inserted by placing the refresh
address on A0–A7 and the RFSH
output is driven Low.
