Guaranteed but not tested.
Output pin capacitance is the capacitive load for any three-stated output pin.
Bidirectional pins: D0-D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, HD0-HD7/HAD0-HAD7.
Input only pins: RESET, IRQ2, BR, MMAP, DR0, DR1, HSEL, HSIZE, BMODE, HMD0, HMD1, HRD/HWR, HWR/HDS, PWD, HA2/ALE, HA1-0.
Input only pins: CLKIN, RESET, IRQ2, BR, MMAP, DR0, DR1, HSEL, HSIZE, BMODE, HMD0, HMD1, HRD/HWR, HWR/HDS, PWD, HA2/ALE, HA1-0.
Output pins: BG, PMS, DMS, BMS, RD, WR, A0-A13, DT0, DT1, CLKOUT, HACK, FL0.
Although specified for TTL outputs, all ADSP-21msp58/59 outputs are CMOS-compatible and will drive to V
Idle refers to ADSP-21msp58/59 state of operation during IDLE instruction. Deasserted pins are driven to either V
Three-statable pins: A0-A13, D0-D23, PMS, DMS, BMS, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RSF1, HD0-HD7/HAD0-HAD7.
