required because some targets are so fast that there is no time between

enabling its receiver then he will not receive the response correctly.
CONFIG_MB_FUNC_HANDLERS_MAX - Maximum number of Modbus functions codes the
protocol stack should support. The maximum number of supported Modbus
functions must be greater than the sum of all enabled functions in this
file and custom function handlers. If set to small adding more functions
will fail.
CONFIG_MB_FUNC_OTHER_REP_SLAVEID_BUF - Number of bytes which should be allocated for the Report Slave ID command. This number limits the maximum size of the additional segment in the report slave id function. See eMBSetSlaveID() for more information on how to set this value. It is only used if CONFIG_MB_FUNC_OTHER_REP_SLAVEID_ENABLED is set to 1.
CONFIG_MB_FUNC_OTHER_REP_SLAVEID_ENABLED - If the Report Slave ID function should be enabled.
CONFIG_MB_FUNC_READ_INPUT_ENABLED - If the Read Input Registers function should be enabled.

CONFIG_MB_FUNC_WRITE_HOLDING_ENABLED - If the Write Single Register function should be enabled.
CONFIG_MB_FUNC_WRITE_MULTIPLE_HOLDING_ENABLED - If the Write Multiple registers function should be enabled.
CONFIG_MB_FUNC_READ_COILS_ENABLED - If the Read Coils function should be enabled.
