Description
Multipurpose pin: Profile Select Pin (PS2) in Direct Switch Mode, Parallel Port Address Line (ADR5), and
Data Line (D5) to program registers.
Multipurpose pin: Profile Select Pin (PS1) in Direct Switch Mode or Linear Sweeping Mode, Parallel Port
Address Line (ADR4), and Data Line (D4) to program registers.
Multipurpose pin: Profile Select Pin (PS0) in Direct Switch Mode or Linear Sweeping Mode, Parallel Port
Address Line (ADR3), and Data Line (D3) to program registers.
Digital Power Supply (1.8 V).
Digital Ground.
Parallel Port Address Line 2 and Data Line 2.
Parallel Port Address Line 1and Data Line 1.
Parallel Port Address Line 0 and Data Line 0.
Clock Out. The profile pins [PS0:PS2] and the IO_UPDATE pin (Pin 27) should be set up to the rising
edge of this signal to maintain constant pipe line delay through the device.
Serial Port and Parallel Port Selection. Logic low = serial mode; logic high = parallel mode.
Analog Ground.
