TXT12 - Teletext register 12 (READ only)
625/525 SYNC
ROM VER R0 to R4
TXT ON
VIDEO QUALITY
A 625 line CVBS signal (logic 0), or a 525 line CVBS signal (logic 1) is being input.
Mask programmable to identify character set version.
Teletext power has been applied to the device (logic 1).
CVBS input can be locked on by the teletext decoder (logic 1).
TXT13 - Teletext register 13 (READ only)
TXT I/FACE BUSY
Text interface busy and no access for either READ or WRITE is allowed to SFRs
TXT0 to TXT11 (logic 1). This register bit performs the software handshake to the teletext
control registers.
