need resources on Microwire 3 Wire interface eeprom control

[EDWARD]

i have a pic16f73 at 4 mhz. i have a microchip 93c46 eeprom connected to the pic. i am tring to write variables to the eeprom before powerdown and then recall them at power up. i cant find any webpages or anything that even shw what commands to use. imm pretty sure i can't use I2CREAD commands. i have a picture of my layout. i just need to get pointed in the right direction. i think i need the microwire 3 wire interface, is this right?

I only have like 6, single byte sized variables i need saved, and they are only updated if they are changed and then pic is shutdown, and they arent changed that often.

also, does the 16f73 have onboard eeprom? and do i need to define stuff before i can use it? i have looked mad hard at the datasheets.
