Detailed Description

CIA 2 Generates NMIs located at $DD00-$DDFF

Member Function Documentation

void c64cia2::interrupt ( bool  state )

inlineprotectedvirtual

Signal interrupt.

Parameters

state

interrupt state

Implements MOS6526.

uint8_t c64cia2::peek ( uint_least16_t  address )

inlinevirtual

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 Bank.

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

inlinevirtual

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 Bank.
