Expand description

Specialized ULA functionality access methods.

Required Methods§

Returns the state of the “late timings” mode.

Sets the “late timings” mode on or off.

In this mode interrupts are being requested just one T-state earlier than normally. This results in all other timings being one T-state later.

Provided Methods§

Returns the last value sent to the memory port 0x7FFD if supported.

    fn ula128_mem_port_value(&self) -> Option<Ula128MemFlags> {
        self.ula.ula128_mem_port_value()
    }

Sets the current value of the memory port 0x7FFD. Returns true if supported. Otherwise, returns false and no writing is performed.

    fn set_ula128_mem_port_value(&mut self, value: Ula128MemFlags) -> bool {
        self.ula.set_ula128_mem_port_value(value)
    }

Returns the last value sent to the memory port 0x1FFD if supported.

    fn ula3_ctrl_port_value(&self) -> Option<Ula3CtrlFlags> {
        self.ula.ula3_ctrl_port_value()
    }

Sets the current value of the memory port 0x1FFD. Returns true if supported. Otherwise, returns false and no writing is performed.

    fn set_ula3_ctrl_port_value(&mut self, value: Ula3CtrlFlags) -> bool {
        self.ula.set_ula3_ctrl_port_value(value)
    }

Returns the last value sent to the memory port 0xFF.

Sets the current value of the memory port 0xFF. Returns true if supported. Otherwise, returns false and no writing is performed.

Returns the last value sent to the memory port 0xF4.

    fn scld_mmu_port_value(&self) -> Option<u8> {
        self.ula.scld_mmu_port_value()
    }

Sets the current value of the memory port 0xF4. Returns true if supported. Otherwise, returns false and no writing is performed.

    fn set_scld_mmu_port_value(&mut self, value: u8) -> bool {
        self.ula.set_scld_mmu_port_value(value)
    }

Returns the last value sent to the register port 0xBF3B.

Sets the current value of the memory port 0xBF3B. Returns true if supported. Otherwise, returns false and no writing is performed.

Returns the last value sent to the data port 0xFF3B.

Sets the current value of the memory port 0xFF3B. Returns true if supported. Otherwise, returns false and no writing is performed.
