Format sense and control are accomplished via connection of the CP500 automation lines
connected to DA20 CTRL0 through CTRL7. The DA20 monitors the CTRL lines to detect
when various formats are selected and asserts Format 10 depending on which mode the
DA20 is in. In all cases, the control lines must be low for a minimum of 80ms to be
recognized as valid format assertions. The DA20 will assert various control lines
depending on which mode is selected on the DA20. See the DA20 Users’ Manual for
specific information related to the DA20 modes of operation and the Auto Digital feature.
The DA20 switches to Format 05 by holding CTRL2 low for approximately 150ms and
returns to Format 10 by asserting CTRL4 low for approximately 150ms.
