Bidirectional pins: D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7.
Input only pins: RESET, BR, DR0, DR1, PWD.
Input only pins: CLKIN, RESET, BR, DR0, DR1, PWD.
Output pins: BG, PMS, DMS, BMS, IOMS, CMS, RD, WR, PWDACK, A0, DT0, DT1, CLKOUT, FL2–0, BGH.
Although specified for TTL outputs, all AD73422 outputs are CMOS-compatible and will drive to VDD and GND, assuming no dc loads.
Guaranteed but not tested.
Three-statable pins: A0–A13, D0–D23, PMS, DMS, BMS, IOMS, CMS, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RFS1, PF0–PF7.
