Write Block with a Word Count, Non-Handshake

The second operand address points to a parameter list containing the following 2 parameter(s):

1. Word Count
2. Starting address of the block

The block is terminated normally by exhausting the word count. The timing of the pipeline transfer is controlled by a DIPswitch on the control board. The cycle time may be selected in units of 20ns. Following the last data cycle, the SSP waits a fixed time (determined by microcode) before terminating the operation (dropping AS).
