Pixel alignment [9:8]
Pixel alignment [9:8]: These registers form a 10-bit horizontal pixel position from the falling edge of horizontal
sync, where the VDP controller initiates the program from one line standard to the next line standard, for
example, the previous line of teletext to the next line of closed caption. This value must be set so that the switch
occurs after the previous transaction has cleared the delay in the VDP, but early enough to allow the new
values to be programmed before the current settings are required.
The default value is 0x1E and has been tested with every standard supported here. A new value is needed
only if a custom standard is in use.

Global line mode [7:0]
Global line mode [7:0]: VDP processing for multiple lines set by the VDP start line register at subaddress D6h
and the VDP stop line register at subaddress D7h.
Global line mode register has the same bit definition as the general line mode registers.
General line mode has priority over the global line mode.
