INV
I
ECL
Digital output polarity inversion input.
This is an ECL level input. This input
inverts the polarity of the digital outputs
P1D0 to P1D5, and P2D0 to P2D5.
(Refer to the Output Code Table.) When
left open, this signal is maintained at the
low level.

TTL
These pins are for the 6 bits of digital
output data for DMPX port 1. P2D5 is the
MSB, and P2D0 is the LSB. These are
TTL levels outputs.
