On the I2C data bus, + * the address is the upper seven bits and the LSB is the "read/write" + * bit. Note that the {i2c_chip} address specified on the command + * line is not shifted up: e.g. a typical EEPROM memory chip may have + * an I2C address of 0x50, but the data put on the bus will be 0xA0 + * for write and 0xA1 for read. This "non shifted" address notation + * matches at least half of the data sheets :-/. + * + * {addr} is the address (or offset) within the chip. Small memory + * chips have 8 bit addresses. Large memory chips have 16 bit + * addresses. Other memory chips have 9, 10, or 11 bit addresses. + * Many non-memory chips have multiple registers and {addr} is used + * as the register index. Some non-memory chips have only one register + * and therefore don't need any {addr} parameter. + * + * The default {addr} parameter is one byte (.1) which works well for + * memories and registers with 8 bits of address space. + * + * You can specify the length of the {addr} field with the optional .0, + * .1, or .2 modifier (similar to the .b, .w, .l modifier). If you are + * manipulating a single register device which doesn't use an address + * field, use "0.0" for the address and the ".0" length field will + * suppress the address in the I2C data stream. This also works for + * successive reads using the I2C auto-incrementing memory pointer. + * + * If you are manipulating a large memory with 2-byte addresses, use + * the .2 address modifier, e.g. 210.2 addresses location 528 (decimal). + * + * Then there are the unfortunate memory chips that spill the most + * significant 1, 2, or 3 bits of address into the chip address byte. + * This effectively makes one chip (logically) look like 2, 4, or + * 8 chips. This is handled (awkwardly) by #defining + * CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the + * {addr} field (since .1 is the default, it doesn't actually have to + * be specified).
