M24LR16E-R
4.3.3
Note:
Delivery of Energy harvesting analog output voltage on the Vout pin depends on the value of
the EH_enable bit of the volatile Control register (see
Table 15.
1. Bit 7 to Bit 1 are read-only bits.
At power-up, in I²C or RF mode, the EH_enable bit is updated according to the value of the
EH_mode bit stored in the non-volatile Configuration byte (see
EH_mode bit is used to configure whether the Energy harvesting mode is enabled or not by
default.
Table 16.
FIELD_ON indicator bit
The FIELD_ON bit indicator located as Bit 1 of the Control register is a read-only bit used to
indicate when the RF power level delivered to the M24LR16E-R is sufficient to execute RF
commands.
During read access to the Control register in RF mode, the FIELD_ON bit is always read
at 1.

When FIELD_ON = 0, the M24LR16E-R is not able to execute any RF commands.
When FIELD_ON =1, the M24LR16E-R is able to execute any RF commands.
EH_mode value
When set to 1, the EH_enable bit enables the Energy harvesting mode, meaning
that the Vout analog output signal is delivered when the P
conditions corresponding to the chosen sink current configuration bit are met (see
Table
When set to 0, the EH_enable bit disable the Energy harvesting mode and the
analog output Vout remains in set in High-Z state.
