Bus Mode Select Header (J19)

5-42
A 3-pin 2 mm planar header enables/disables the GT-64260B SROM
initialization. No jumper or a jumper across pins 1-2 enables the
GT-64260B device initialization via I2C SROM while a jumper across
pins 2-3 disables this initialization sequence. The pin assignments for this
header are as follows:
Table 5-28. SROM Initialization Enable Header (J17) Pin
A 3-pin 2 mm planar header selects the processor bus operating mode. No
