128 bytes
■Minimum bus cycle time
● 77 ns (13.0 MHz)
Note: The bus cycle time here refers to the ROM read speed.
■Minimum instruction cycle time

■OSD
● Screen display: 36 characters × 8 lines
● Display RAM : 352 words (1 word=9 bits)
Display area: 36 words × 8 lines
Control area: 8 words × 8 lines
● Font types: 16×32 font, 256 types (including 5 fixed fonts)
An arbitrary number of characters can be generated as 16×17 or 8×9 font characters.
● Display colors: 512 colors (Analog output)
Character text, background, borders, and full background can be displayed.
A maximum 16 colors displayable on a line.
● Display mode specifiable on a line basis.
OSD mode1, OSD mode 2(Quarter size), OSD mode 3(Simplified graphic), caption/text mode
● Vertical display start line and horizontal display start position specifiable on a line basis.
● Shutter function (specifying the display start or stop line) and scroll functions specifiable on a line basis.
● Horizontal character spacing (9 to 16 dots) (*6) and vertical character spacing (1 to 32 dots) specifiable on a line
basis.
● Character size selectable from 10 character sizes on a line basis. (*6)
(Horizontal×Vertical) = (1×1), (1×2), (2×2), (2×4), (1.5×1), (1.5×2), (3×2), (3×4), (0.5×0.5), (0.75×0.5)
● Simplified graphic display (One character (16×16 font) can be painted in 4 or 8 colors.)
● The half tone control of the TV picture in the background of the character is possible.
● Built-in the oscillation circuit for display
(*6)The supported range varies depending on the active display mode. Refer to the user's guide for details.
■Data slicer function(closed caption format)
● Extracts closed caption data and XDS data.
● NTSC/PAL selectable and line specifiable.
■Ports
● Normal withstand voltage I/O ports
Ports whose I/O direction can be designated in 1 bit units: 10 (P1n, P3n)
Ports whose I/O direction can be designated in 4 bit units: 8 (P0n)
*If X’tal oscillator is to be used for time-of-day clock, the number of available Port 0 is 6.
Note: Threee of the available ports are internally connected to the companion signal processing _IC.
■Timers
● _Timer 0: 16-bit timer/counter with a capture register.
● Timer 1: 16-bit timer/counter that supports PWM/toggle outputs
● Base timer
■SIO
● _SIO0: 8-bit synchronous serial interface
● SIO1: 8-bit asynchronous/synchronous serial interface (bus mode 1 system)
Input and output is possible from the terminal of two systems in bus mode.
The two data lines and clock lines can be connected.
■AD converter: 6 bits ×5 channels
Note: One channel is connected internally to the signal processing IC.
■PWM: 14-bit PWM×1 channel
