Number of words
This register is programmed to trigger an interrupt when the number of words in the FIFO exceeds this value (default
80h). This interrupt must be enabled at address C1h. 1 word equals 2 bytes.
2.20.62 FIFO Reset Register

Any data
Writing any data to this register resets the FIFO and clears any data present.

Field 1 enable
Field 2 enable
Line number
This register is programmed to trigger an interrupt when the video line number matches this value in bits 5:0. This
interrupt must be enabled at address C1h. The value of 0 or 1 does not generate an interrupt.
Field 1 enable:
0 = Disabled (default)
1 = Enabled
Field 2 enable:
0 = Disabled (default)
1 = Enabled
Line number: (default 00h)

Switch pixel [9:8]
These registers form a 10-bit horizontal pixel position from the falling edge of 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.
