FIFO_R_W about mpu6050 HOT 7 OPEN

Dear Friends,
for your reference i add some code what i write for get raw value from accelerometer registers.
i have read accelero meter value with this code
u8 accreg[6]={0x3B,0x3C,0x3D,0x3E,0x3F,0x40,0x00};
u8 read_buffer[8]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};
ret = Ql_IIC_Write_Read(1, addr, accreg, 1,read_buffer, 6); //1-is Channel, addr=0xd0, accreg-is accelero meter registers 1=must be true for communication enable, read_buffer-is read data from slave registers, 6= registers length;
dec_accx=(read_buffer[0]<<8) | read_buffer[1];
dec_accy=(read_buffer[2]<<8) | read_buffer[3];
dec_accz=(read_buffer[4]<<8) | read_buffer[5];
SerialPrint("--AX%d",dec_accx);
SerialPrint("--AY%d",dec_accy);
SerialPrint("--AZ%d",dec_accz);

thank you

Dear kriswiner,
ya that is my question, my controller connect 0xd0 address with Accelerometer, so 0x75 register returns 0x58, my controller read data in only 8bytes in single transmission,

and one thing i am newbie for I2C Communication so i don't know to how to read/write data to the registers

the below code shows my controller how to read data from registers
must i write address for each transmission like
u8 accreg[6]={0x3B,0x3C,0x3D,0x3E,0x3F,0x40,0x00};
this above char store 6 byte address for read 6 registers,
ret = Ql_IIC_Write_Read(1, addr, accreg, 1,read_buffer, 6); //1-is Channel, addr=0xd0, accreg-is accelero meter registers 1=must be true for communication enable, read_buffer-is read data from slave registers, 6= registers length;

my doubt is
if i read single byte data from FIFO 0x74 register that data is still available in same register or that is Automatically erased,
because i send request to read 2nd byte data from same address 0x74 register that is read same data(like first request read data) or not.

sorry for my non grammatical English
I hope you understand my doubt/question

thank you

Dear kriswiner,
thanks for your suggestion that is ok for my project but already board was designed with MPU6050 so i can't change the module,

if you can please help to clear my doubt
if i read first byte from 0x74 FIFO register that byte is still available in FIFO register or that is automatically erased.

thank you'
