T1040RM datasheet error SerDes Register Map description

Hello NXP / Freescale team,

in QorIQ T1040 Reference Manual, Rev. 1, 08/2015 I noted that in register

General Control Register 1 - Lane n (SerDes_LNnGCR1)

the fields

REIDL_EX_SEL

and

REIDL_ET_SEL

are displayed as two-bit fields in the regster overview page 1757.

However in the coming

SerDes_LNnGCR1 field descriptions page 1758

the recommended values are stated as three-bit values:

PCIe: 011 (2.5 Gbaud)

SGMII-1G: 011 (1.25 Gbaud)

SGMII-2.5G: 000 (3.125 Gbaud)

Probably a mistake?

Best regards,

Stefan Lange

Sorry,

should have read on.

The

REIDL_EX_MSB

resp.

REIDL_ET_MSB

most significant bit is in a different field.

Sorry for creating the buzz.

Best regards,
Stefan
