Expand description

Represents a contiguous block of memory which can be read, written, reset, and polled to see if an interrupt has been triggered.

Required Methods§

source

fn read(&mut self, address: u16) -> u8

Read a byte from this memory at the given address. Implementations may trigger side effects as a result of this read.

source

fn write(&mut self, address: u16, value: u8)

Write a byte to this memory at the given address.

source

fn reset(&mut self)

Reset this memory to its initial state, e.g. after a system reboot. Sometimes this will clear the contents of the memory, like with RAM. Other times this is a no-op, e.g. for ROM.

source

fn poll( &mut self, cycles_since_poll: u64, total_cycle_count: u64 ) -> ActiveInterrupt

Poll this memory to see if an interrupt has been triggered. Implementations may trigger an NMI or IRQ for any implementation-dependent reason.
