Here is the excerpt from the errata :
Workaround: If the interval between 60h and its subsequent command can be guaranteed within 20μs, Option I is recommended, otherwise Option II (involves hardware) should be selected. Option I: The table below lists the detail command sequences: Command Data bus Address bus Remarks Sequence 1 90h Block Address Read Lock Status 2 Read Block Address + 02h (2)(3) (1) 3 60h Block Address (2)(3) (1) Lock/Unlock/RCR Configuration 4 D0h/01h/03h Block Address Notes: (1) Block Address refers to RCR configuration data only when the 60h command sequence is used to set RCR register combined with 03h subsequent command. (2) For the third and fourth command sequences, the Block Address must be the same. (3) The interval between 60h command and its subsequent D0h/01h/2Fh/03h commands should be less than 20μs.
Please add this workaround text from the errata to the commit text in your next patch version. This makes things easier - no need to search for the errata.
OK
Philippe
