'''NOTES'''
1. The function of these this I/O ports port is dependant on the CRTC type
2. The CRTC is not connected to the CPU's RD and WR pins, so the CRTC is not aware of the CPU bus I/O direction. Therefore, if you perform an IN instruction to the select or write functions, it will write data to the CRTC from the current data on the bus.
