GENERAL DESCRIPTION
MTV021 is designed for monitor applications to
display built-in characters or fonts onto monitor
screens. The display operation occurs by transferring
data and control information from the micro-controller
to RAM through a serial data interface. It can execute
full-screen display automatically, as well as specific
functions such as character background color, bor-
dering, shadowing, blinking, double height and width,
font by font color control, frame positioning, frame
size control by character height and row-to-row spac-
ing, horizontal display resolution, full-screen erasing,
fade-in/fade-out effect, windowing effect and shad-
owing on window.
MTV021 provides 256 standard and 16 multi-color
characters and graphic fonts for more efficacious
applications. The full OSD menu is formed by 15
rows x 30 columns, which can be positioned any-
where on the monitor screen by changing vertical or
horizontal delay.
Moreover, MTV021 also provides 8 PWM DAC
channels with 8-bit resolution and a PWM clock out-
put for external digital-to-analog control.

The data transmission is permitted to change from format (a) to format (b) and (c), or from format (b) to format
(a), but not from format (c) back to format (a) and (b). The alternation between transmission formats is config-
ured as the state diagram shown in Figure 3.

3.2 Address bus administrator
The administrator manages bus address arbitration of internal registers or user fonts RAM during external
data write in. The external data write through serial data interface to registers must be synchronized by inter-
nal display timing. In addition, the administrator also provides automatic increment to address bus when exter-
nal write using format (c).
3.3 Vertical display control
The vertical display control can generates different vertical display sizes for most display standards in current
monitors. The vertical display size is calculated with the information of double character height bit(CHS), verti-
cal display height control register(CH6-CH0).The algorithm of repeating character line display are shown as
Table 2 and Table 3. The programmable vertical size range is 270 lines to maximum 2130 lines.
The vertical display center for full screen display could be figured out according to the information of vertical
starting position register (VERTD) and VFLB input. The vertical delay starting from the leading edge of VFLB,
is calculated with the following equation:
Vertical delay time = ( VERTD * 4 + 1 ) * H
Where H = one horizontal line display time

PWMCK - Select the output options to HTONE/PWMCK pin.
= 0 ⇒ HTONE option is selected.
= 1 ⇒ PWMCK option is selected with 50/50 duty cycle and synchronous with the input HFLB.
The frequency is selected by (VCO1, VCO0) shown as Table 5.
The initial value is 0 after power up.
SELVCL - Enable auto detection for horizontal and vertical syncs input edge distorition to avoid unstable
Vsync leading mismatch with Hsync signal while the bit is set to "1". The initial value is 0 after
power up.
HSP -
= 1 ⇒ Accept positive polarity Hsync input.
= 0 ⇒ Accept negative polarity Hsync input.
VSP -
= 1 ⇒ Accept positive polarity Vsync input.
= 0 ⇒ Accept negative polarity Vsync input.
VCO1, VCO0 - Select the appropriate curve partitions of VCO frequency to voltage based on HFLB input and
horizontal resolution register (HORR). And there are different curve partitions based on differ-
ent application resister value on pin 3 (pin RP) as belows:
(i) 12K ohm:
= (0, 0) ⇒ 6MHz < Pixel rate < 12MHz
= (0, 1) ⇒ 12MHz < Pixel rate < 24MHz

= (1, 1) ⇒ 56MHz < Pixel rate < 96MHz
(iv)9.1K ohm:
= (0, 0) ⇒ 7.5MHz < Pixel rate < 15MHz
= (0, 1) ⇒ 15MHz < Pixel rate < 30MHz
= (1, 0) ⇒ 30MHz < Pixel rate < 60MHz
= (1, 1) ⇒ 60MHz < Pixel rate < 96MHz
(v)8.2K ohm:
= (0, 0) ⇒ 8MHz < Pixel rate < 16MHz
= (0, 1) ⇒ 16MHz < Pixel rate < 32MHz
= (1, 0) ⇒ 32MHz < Pixel rate < 64MHz
= (1, 1) ⇒ 64MHz < Pixel rate < 96MHz
(vi)7.5K ohm:
= (0, 0) ⇒ 8.5MHz < Pixel rate < 17MHz
= (0, 1) ⇒ 17MHz < Pixel rate < 34MHz
= (1, 0) ⇒ 34MHz < Pixel rate < 68MHz
= (1, 1) ⇒ 68MHz < Pixel rate < 96MHz
(vii)under or equal to 6.2K ohm:
= (0, 0) ⇒ 9.5MHz < Pixel rate < 19MHz
= (0, 1) ⇒ 19MHz < Pixel rate < 38MHz
= (1, 0) ⇒ 38MHz < Pixel rate < 76MHz
