Fast Initiate
On receiving the Fast Initiate command, the M24LR16E-R sets the internal Initiate_flag and
sends back a response only if it is in the Ready state. The command has to be issued in the
Non Addressed mode only (Select_flag is reset to 0 and Address_flag is reset to 0). If an
error occurs, the M24LR16E-R does not generate any answer. The Initiate_flag is reset after
a power-off of the M24LR16E-R. The data rate of the response is multiplied by 2.
The subcarrier_flag should be set to 0, otherwise the M24LR16E-R answers with an error
code.
The request contains:
Table 93.
The response contains:
Table 94.

When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Fast Initiate command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
