T1042 SERDES PLL Lock Time

Question asked by Dean Rametta on Oct 31, 2018

The T1040 Reference Manual (section 4.6.1) describes the device's power on reset sequence. After step 18, there is a note indicating that the software should check that the SERDES PLL has locked. This is indicated by the SerDesx_PLLnRSTCTL[RST_DONE] field. What action should be taken if the verification fails? Should the code allow time for the PLL lock to complete? If so, how long should it take? Thanks in advance for your help.
