reading silicon die information from OTP

I'm curious what various revs of silicon there are out there. I have a rev D STR912FW44 datecode 646 chip, and the upper word of the OTP reads: 0x9113.

// 9 = major family (STR9)

// 1 = minor family (STR912)

// 1 = major mask

// 3 = minor mask.

You can use this code to read it out.

uint32_t rev = (FMI_ReadOTPData(FMI_OTP_WORD_7) >> 16);

char buffer[32];

sprintf(buffer,''Die: %04X\n'',rev);

The FA documentation says that this should be 0x9103 [sic] for the rev D FW44 chip, and 0x9120 for the FAW44.

As we've discovered recently, there was a mask change between date code 646 and date code 710.

Can anyone with a 710 chip please read out this data and report it?
