Member Function Documentation

interrupt()

void libsidplayfp::c64cia2::interrupt ( bool  state )

inlineoverrideprotectedvirtual

Signal interrupt.

Parameters

state

interrupt state

Implements libsidplayfp::MOS652X.

peek()

uint8_t libsidplayfp::c64cia2::peek ( uint_least16_t  address )

inlineoverridevirtual

Bank read. You probably should override this method, except if the Bank is only used in write context.

Parameters

address

value to read from

Returns

value at address

Implements libsidplayfp::Bank.

poke()

void libsidplayfp::c64cia2::poke ( uint_least16_t  address, uint8_t  value  )

inlineoverridevirtual

Bank write.

Override this method if you expect write operations on your bank. Leave unimplemented if it's logically/operationally impossible for writes to ever arrive to bank.

Parameters

address	address to write to
value	value to write

Implements libsidplayfp::Bank.
