Writing 1-word/2-word data to a module (16-bit specification)
TO(P), DTO(P)
• TO(P): These instructions write the n points of data from the specified device to the buffer memory in the module/host CPU
module.
• DTO(P): These instructions write the n

2 points of data from the specified device to the buffer memory in the module/host
CPU module.
