Serial Presence Detect Information

A serial presence detect storage device - E2PROM -

is assembled onto the module. Information about the

module configuration, speed, etc. is written into the

SPD-Table for modules:

E2PROM device during module production using a se-

rial presence detect protocol (I2C synchronous 2-wire

bus)
