//  Big modification history
// LLY2.01, extend the GPIO R/W API, that it can specify the group

// LLY2.04, remove the un-necessary global variables
// ex. 908 used only (register related variables)
//     temp global variables

// LLY2.05, remove the un-necessary code
// - HAL_SetSectorFormat() since nobody ues it now.

// LLY2.10, remove CT909A related code

// LLY2.11, remove pin related define to pio.h
// ex. IOMUTE/ EEPROM_SCK/ EEPROM_DAT/ SCART_SW/ SCART_TV/ SCART_RGB
