About CD pin of MCIMX6DL-SDP at SD Bootting

In MCIMX6DL-SDP,
Is CD signal used when it boots from SD2 port?

 

According to the reference manual and Datasheet, for USDHC-2 boot, GPIO_4 (R6 pin) is used as a CD signal.

 

ReferenceManual: (IMX6DLRM.pdf Rev1)
- Table 8-18. SD/MMC IOMUX Pin Configuration(P.425)
- Table 67-2. USDHC2 External Signals(P.5540)

 

DataSheet: (IMX6DLIEC.pdf Rev2.1)
- Table 89. Interface Allocation During Boot(P.133)

 

However, in MCIMX6DL-SDP, GPIO2_2 (F16 pin) is used.

These have inconsistency.

 

Should GPIO2_2 (F16 pin) be used in order to boot from SD2 port?

 

Best regards,
