/* These are memory addresses as would be seen by one or more EEPROM * chips strung on the I2C bus, usually by manipulating pins 1-3 of a * set of EEPROM devices.

It also includes the top 3 bits of the 19 bit EEPROM memory * address, namely bits 18, 17, and 16. This makes up the 7 bit * address sent on the I2C bus with bit 0 being the direction bit, * which is not represented here, and sent by the hardware directly. * * For instance, * 50h = 1010000b => device type identifier 1010b, bits 18:16 = 000b, address 0. * 54h = 1010100b => --"--, bits 18:16 = 100b, address 40000h. * 56h = 1010110b => --"--, bits 18:16 = 110b, address 60000h. * Depending on the size of the I2C EEPROM device(s), bits 18:16 may * address memory in a device or a device on the I2C bus, depending on * the status of pins 1-3.
