MPL3115A2 Turn-on time specification

In the Electrical Characteristics section of the mpl3115a2 data sheet (page 6),

item 14 is the Turn-on time. In 128os mode, it's specified at 1000 ms.

This is the amount of time you have to wait for "valid data" after exiting

standby mode and entering active mode.

I don't see this delay implemented in any of the sample mpl3115a2 drivers posted on

the internet or on this website. I would expect to see code as follows, with a 1000ms

delay after leaving standby and entering active mode:

I2C_WriteRegister(MPL3115A2_I2C_ADDRESS, CTRL_REG1, 0xB9); // Active altitude mode, OSR = 128

delay_ms(1000);

// then toggle the one-shot, wait for Data Ready, and read the data.

Is the Turn-on Time specification real, or can it safely be ignored ?

Also can the forum Moderator please contact me. I set my profile

to use my "handle" instead of my name, but this setting is ignored.
