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
SPD-Table:
written into the E2PROM device during module pro-
duction using a serial presence detect protocol (I2C
synchronous 2-wire bus)
