Block transfer write instructions

These instructions terminate normally when the word count is exhausted. The PSW and updated NTA are not stored anywhere on normal termination.

If the block transfer terminates because of an SS!=0 response, the PSW and updated NTA will be stored in DM 0 and DM 4. The NTA will be 8 greater than the address of the last data written. The number of words transferred will be the NTA minus the starting address divided by 4 minus 2.
