Serial Presence Detect Information
A serial presence detect storage device –
E2PROM – is assembled onto the module. Informa-
tion about the module configuration, speed, etc. is
writtenintothe E2PROM device during module pro-
duction using a serial presence detect protocol (I2C
synchronous 2-wire bus)
