2.3.12 Calibration Bus Signals
Calibration signals function only when using the 496 pin assembly.
2.3.12.1 Calibration Chip Select 0 / GPIO
CAL_CS
[0]
CAL_CS[0] is the primary function and selects the primary chip for calibration.
2.3.12.2 Calibration Chip Select / Calibration Address
CAL_CS
[1:3]_CAL_ADDR[9:11]
CAL_CS[1:3] are the primary functions that select the primary chip for calibration. The alternate 
functions are calibration address signals. These signals are functional only when using the 496 pin 
assembly.
2.3.12.3 Calibration Address
CAL_ADDR[12:30]
CAL_ADDR[12:30] are the calibration addresses. They are functional only when using the 496 pin 
assembly. 
2.3.12.4 Calibration Data 
CAL_DATA[0:15]
CAL_DATA[0:15] is the primary function and is a calibration address. It is functional only when using 
the 496 pin assembly. 
2.3.12.5 Calibration Read/Write
CAL_RD_WR
CAL_RD_WR is the primary function and is a calibration read/write signal function. It is functional only 
when using the 496 pin assembly. 
2.3.12.6 Calibration Write/Byte Enable
CAL_WE
/BE[0:1]
CAL_WE/BE[0:1] is the primary function and is a calibration write enable and byte enable. It is functional 
only when using the 496 pin assembly. 
2.3.12.7 Calibration Output Enable
CAL_OE
CAL_OE is the primary function and is a calibration output enable. It is functional only when using the 
496 pin assembly.
