Parameters are:

ItemBit LengthDescription
SlaveAddr 8 An 8-bit slave address
RegAddr16 16 The 16-bit, 0-based address of a holding register (4xxxx reference) in the slave.
ItemCount 8 An 8-bit count of how many 16-bit registers are to be written in the slave. The minimum is 1. The maximum is determined by available communications buffer size (documented elsewhere). ItemCount contiguous items will be written.
SPAddr16

16

A 16-bit RAM address within the SPLat master's RAM.
NumberFormat 8 Specifies the number format sent from the slave, either byte (8 bits), word (16 bits, standard) or float together with the endianness of the value.
