„Data-Slicer
• XDS
1) Supports XDS-1X and XDS-2X (With auto-recognition)
• VPS/PDC/PAL-WSS
Data-slicer can choose one of the following three formats to the TV Line(VBI).
1) PDC/UDT and other Teletext data
2) VPS
3) PAL-WSS
• VPS
• EPG-J
• Antiope
• VBID(VideoID)
„Universal Remote Control Transmitter Circuit
• Outputs remote control signal from PF4/IRP terminal.
„Interrupts
• 36 sources, 10 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control.
Any interrupt requests of the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level
takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.
No.

• Priority Level: X > H > L
• Of interrupts of the same level, the one with the smallest vector address takes precedence.
„Subroutine Stack Levels
• 4096 levels maximum (the stack is allocated in RAM.)
„High-speed Multiplication/Division Instructions
• 16 bits × 8 bits
(5 tCYC execution time)
• 24 bits × 16 bits (12 tCYC execution time)
• 16 bits ÷ 8 bits
(8 tCYC execution time)
• 24 bits ÷ 16 bits (12 tCYC execution time)
„Oscillation Circuits
• RC oscillator circuit (internal): For system clock
• CF oscillator circuit: For system clock with internal Rf
• Crystal oscillator circuit: For low-speed system clock
• Multifrequency RC oscillator circuit (internal): For system clock
