RF430F5978 3d wake up timing in milliseconds

Hi,

How long does it takes to wake microcontroller up from 3D LF reader in the worst case?

I mean absolute time (ms) for Wakeburst + SOF + Wake Pattern (24 bit) + EOF

    Bit timings are shown here in the RF430F59xx family users guide, www.ti.com/.../slau378.pdf , see page 767 and on.

    Dear Josh,
    I look through datasheet but can't compose real timing based on a lot of graphics and tables. I do not understand this technology thoroughly, but just want to evaluate if it suitable moving railway container identifying. So I need to understand minimum-maximum (or typical/recommended) time needed for 3D Wake up process. It’s not a problem to calculate timing for sending 433 MHz RF packet, but 3D LF packet is hard to understand.
    I see some real figures for bit timing (table Table 24-19) but how many bits will include full wake-up sequence from t_wake till EOF?
