hi all!
I tried to read Multiple Data Bytes from the TWI. But I always get a value of 0xFF.
The program is strictly based on the reference ATMEL company still has problems.
my code:
[code]
AT91C_BASE_TWI->TWI_MMR = 0;
AT91C_BASE_TWI->TWI_MMR = (2 << 8) | AT91C_TWI_MREAD | (0x50<< 16);

// Set internal address bytes
AT91C_BASE_TWI->TWI_IADR = 0;

// Send START condition
AT91C_BASE_TWI->TWI_CR = AT91C_TWI_START;

for(W=0;W<3;W++){
while(!((AT91C_BASE_TWI->TWI_SR&AT91C_TWI_RXRDY)==0));
buf[W]=AT91C_BASE_TWI->TWI_RHR;
}
TWI_Stop(AT91C_BASE_TWI);
[/code]
my micro is sam7x256 , EEPROM IC is 24c32.
