A sequence value of 1 indicates that the signal is in the first group to engage during plugging of a module. A sequence value of 2
indicates that the signal is the second and last group. The two guide pins on the connector are electrically connected to the transceiver circuit
ground. These two guide pins make contact with circuit prior to sequence 1 signals.

Serial module definition
protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, MOD-DEF(1:2) appear as no connector
(NC) and MOD-DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the
2-wire serial CMOS E²PROM protocol of the ATMEL AT24C01A/02/04 family of components.
