Fields§

§address: RW<u16>

VRAM Address 0-16 (offset 0x00)

§address_hi: RW<u8>

ADDRx_H - Address (offset 0x02)

§data0: RW<u8>

DATA0 - VRAM Data port 0 (offset 0x03)

§data1: RW<u8>

DATA1 - VRAM Data port 1 (offset 0x04)

§control: RW<ControlFlags>

CTRL - Control, offset 0x05

§irq_enable: RW<u8>

IEN - Interrupt enable, offset 0x06
