ADDRESSING
DISPLAY RAM
1 k-Byte SRAM (512
×
16 bits) is built in S5D2510. Registers are distributed within 16 rows
×
30 columns. But, for
facilitating internal calculation, addressing is done using exponents of 2, and the S5D2510 is composed of 16
rows
×
32 columns RAM Cell.
if 'Erase' Bit of "Frame Control Register 0" is enabled by setting '1' and erased RAM, 480 RAM cells are erased
excepting only 16th row (Frame Control Registers). Therefore, the 'Erasing Time' is measured with 480 RAM
cells as the standard.
* Erasing Time
Erasing Time = RAM Clock x 480 (RAM Cell volume)
RAM Clock = 12 dot clock
Dot Clock = 1/ (dot frequency)
Dot Frequency = Horizontal Frequency x Resolution (mode)
So, the maximum value of the 'Erasing Time' is as follows.
(Erasing Time)
MAX
= (12 x 480) / (30k x 640) = 30ms
When you are programming with MCU, you have not to give the S5D2510 other operation or command during
the (Erasing Time)
MAX
at a minimum, if you hope that timing violation isn't happened.
ROM FONTS
S5D2510 provides 464 ROM fonts for displaying OSD icons, which allows the use of multi-language OSD icons.
Out of the 464 ROM fonts, 448 are standard fonts, and 16 are multi-color fonts. The standard font is placed at
000h address is reserved for blank data. Each multi-color font is composed of 4 color attribute ROM fonts are as
shown "Figure III-4.2 : Composition of ROM Fonts".
A multi-color font is made by 'OR operating with these 3 fonts. When you want to access this multi-color font, you
may call the address of R-color attribute font. In example, the addresses of 1C0h, 1D0h and 1E0h mean
respectively R, G, B color attribute fonts. and that the multi-color font is accessed by addressing 1C0h is made
with 1C0h, 1D0h, and 1E0h through 'OR' operation.
To do addressing 464 ROM fonts, as explained at "Memory Map (12p)", the S5D2510 uses 9 bits added 1
extended bit which use the MSB of row/ column address and 8 bits for character code bits in "Character &
Attribute Registers".
