For valid device address ranges, see "Device Addresses" on page 2-1.
When Mode 0 is selected, source devices S1 and S2 and destination device D1 occupy 3 consecutive data registers starting with the designated
device.
When Mode 1 is selected, source device S1 and destination device D1 occupy 7 consecutive data registers starting with the designated device.
Source device S2 occupies 3 consecutive data registers starting with the designated device.
Since the TSUB instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.
