Member Function Documentation

◆ interrupt()

void libsidplayfp::c64cia1::interrupt ( bool state )

inlineoverrideprotectedvirtual

Signal interrupt.

Parameters

state interrupt state

Implements libsidplayfp::MOS6526.

◆ peek()

uint8_t libsidplayfp::c64cia1::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::c64cia1::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
