SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
M37274MA-XXXSP
PRELIMINARY
Notice: This is not a final specification.
Some paramentic limits are subject to change.
MITSUBISHI MICROCOMPUTERS
(13) Scan Mode
M37271MF-XXXSP has the bi-scan mode for corresponding to H
SYNC
of double speed frequency. In the bi-scan mode, the vertical start
display position and the vertical size is two times as compared with
the normal scan mode. The scan mode is selected by bit 1 of the
OSD control register (refer to Figure 55).
(14) Window Function
This function sets the top and bottom boundary of display limit on a
screen. The window function is valid only in the CC mode. The top
boundary is set by window H registers 1 and 2. The bottom bound-
ary is set by window L registers 1 and 2. This function is turned on
and off by bit 5 of the OSD control register (refer to Figure 55).
The structure of window H registers 1 and 2 is shown in Figure 86,
the structure of window L registers 1 and 2 is shown in Figure 87.
Notes 1:
Set values except “00
16
” and “01
16
” to the window H regis-
ter 1 when the window H register 2 is “00
16
.”
2:
Set the register value fit for the following condition :
(WH1 + WH2) < (WL1 + WL2)
