 - You can plug and unplug the programmer device (CH341A) to the USB port at any time when basic operations (reading, checking, and programming) are not in progress.
 
 ### Chip type selecting
-Select the type of chip used from the `Type` pop-up menu: `SPI FLASH` when using SPI NOR FLASH chips of the `25xxx` series, `24_EEPROM` when using i2c EEPROM of the `24xxx` series, `93_EEPROM` when using MicroWire EEPROM of the `93xxx` series.

 When using `25xxx` series SPI NOR FLASH chips, the `Detect` button will be available. When the `Detect` button or ![Detect](img/test64.png) or `<Ctrl+D>` is pressed, the JEDEC information is read from the chip and all parameters of that chip are loaded from the chip database. Any parameter (`size`, `page size`, `block size`, `VCC voltage`, `and 4-bit address length`) can be changed manually.  You can manually enter the `Manufacture` and `Name` pop-up menu data - all other parameters will be automatically loaded from the chip database.

 ## Revision history
 - Ver. 1.0.0 - 1.0.18 - Partially working versions.
-- Ver. 1.0.19 - Fixed wrong level on SDA pin in i2c EEPROM. Removed old function "ch341a_spi_init" in file "ch341spi.c", replaced by "ch341a_init" (this is SNANDer bug).
+- Ver. 1.0.19 - Fixed wrong level on SDA pin in I2C EEPROM. Removed old function "ch341a_spi_init" in file "ch341spi.c", replaced by "ch341a_init" (this is SNANDer bug).
 - Ver. 1.0.20 - Fixed incorrect byte sequence when reading/writing Microwire EEPROM in 16 bitmode (The SNANder program file "bitbang_microwire.c" bad functions - Write_EEPROM_3wire, Read_EEPROM_3wine replaced to Write_EEPROM_3wire_param, Write_READ_3wire_param).
 - Ver. 1.0.21 - Working, unstable version
 - Ver. 1.0.22 - Working, stable version. Added languages. Added font colour compatibility in light and dark interface theme.
