M24LRxx_Get_Energy_Harvesting_Range function

This function returns the range of energy harvesting using the Configuration byte retrieved

with a Read Cfg command.

M24LRxx_Get_RF_BUSY_WIP function

This function returns the RF busy or Write in progress bit using the Configuration byte

retrieved with a ReadCfg command.

Table 143.

M24LRxx_Get_Energy_Harvesting_Range function description

Prototype

u8 M24LRxx_Get_Energy_Harvesting_Range( u8

Configuration_Byte);

Input parameter

Configuration_Byte: the byte containing the data available in the tag structure

at dataField [M24LRxx_CONFIGURATION_BYTE_CURSOR]

Output parameter

None

Return parameter

M24LRxx_CONFIGURATION_BYTE_RANGE_6_MA: The energy harvesting is

activated when at least 6 mA can be retrieved.

M24LRxx_CONFIGURATION_BYTE_RANGE_3_MA: The energy harvesting is

activated when at least 3 mA can be retrieved.

M24LRxx_CONFIGURATION_BYTE_RANGE_1_MA: The energy harvesting is

activated when at least 1 mA can be retrieved.

M24LRxx_CONFIGURATION_BYTE_RANGE_300_MA: The energy

harvesting is activated when at least 300 µA can be retrieved.
