ImodbusRTUAdr()

ImodbusRTUAdr() sets the start addresses of M and D memory.

void ImodbusRTUAdr(uint16_t m_offset, uint16_t d_offset)

Commands

Command	Arguments	Return Value	Operation
`ImodbusRTUAdr(m_offset, d_offset)`	`uint16_t m_offset` `uint16_t d_offset`	`void`	Sets the start addresses of M and D memory.

ImodbusRTUAdr(0, 0);

Keep calling the Slave or Master execution function in loop().
The data array size must be at least the requested quantity.
Do not treat return codes BUSY and IDLE as communication failures.
When sharing M and D with Cnet/MC Protocol, define a single final size and initialization order. Do not call ImodbusRTUMem() or ICnetMem() again at runtime.
Memory allocation functions do not return success status. For nonzero sizes, verify that M and D are not nullptr before accessing them in user code.
