How to use ATTiny2313 or ATMega8A for VSTA1SPL (Sharp, with Toshiba TD6358P or eqivalent) TV I2C tuner control (for example , for receiving repeaters 144.000-145.750 , 431.000-438.750 MHz, 3 band RF-scanner ) with LED 7 segments or 1602 display (English)? How to flash 2-nd IF, 1st IF for device or how to use it for 90 channel TV programm switcher?
Surely, that will all be described in the documentation for the VSTA1SPL ?
As far as the ATTiny2313 or ATMega8A (or any other microcontroller, for that matter) is concerned, it's just a matter of sending & receiving bytes over I2C.
Here, Fleury is the widely recommended library for I2C ...

As you seem to be flooding the forum with "How do I interface to X" questions, see: How To Interface Anything To Anything Else.
What's more you have been doing it in the wrong forum. The "projects" section is for announcing new (complete) projects you have posted. Please do not use it for posting new threads.
Also surely you could have asked all the questions in a single thread?

This is a I2L tuner (pseudo -TWI), but this is a not I2C 8 *3 bit with ACK bits ( using I2C_Init_Master(); I2C_Start(); I2C_SendByte(Addr); I2C_SendByte(Data1); I2C_SendByte(Data2); ... I2C_Stop(); ).
Examples of units for data sending tgo tuner are in the attach

Could not understand how to select bands for frequency from datasheet (VHF-L,VHF-H,UHF , ... ), how to use for S bands, Hyperband bands (for similary tuners with this IC, but not this type of tuner )(this is a tuner for 1-12 ch, 1,2 S-band, UHF 21-80 ch. ?)?
That datasheet is from 1999. Is the part even still available? And there isn't a more modern device?
Also the Tiny2313 is probably too small a device to handle what you want to do. The Mega8A might just make it. I am talking about program Flash size that is

Clearly this part is not twi/i2c - it is more like spi.
Also, you’re not supposed to put code in a .h file!
presumably also for analogue TV, then?
do you still have that?
Clearly this part is not twi/i2c
Indeed.
In fact, TWI/I2C is not claimed nor even mentioned anywhere in the document.
It does say that the logic is "I2L" - but that is something entirely different.
you’re not supposed to put code in a .h file!
Indeed not.
There was mention of the amateur radio bands in the OP.
Such tuners have been used as VHF/UHF spectrum analyzers and scanners, largely by hams. Surely, there must be examples out there. Have you tried Your Friend Google with something like: interfacing VSTA1SPL

I did it for the OP....guess what came back?
We are teh ONLY game in town! Boo-YAH!

Pin 13 of IC ( see dastasheet TD6358P ) in VTSA1SPL is unused, BS=0b0001 for BL band, BS=0b0010 for BH band(for repeater R0 145,600 MHz+38MHz or -38MHz ), BS=0b1000 for BU (UHF band, from 21 ch. )
