From the project
68010 SBC using a ATF1608 CPLD based on teh rosco_m68k SBC
A 68010 single-board computer based on the roscom68k r2 design. Simple010 replaces the six discrete glue-logic ICs from that design with a single ATF1508AS PLCC84 CPLD**, reducing board complexity while adding hardware SPI acceleration for SD card access.
1. Glue logic — HALT/RESET open-drain drivers, CPU-space gating, boot flag 2. Address decoder — RAM, ROM, expansion, and I/O selects; DTACK; WR 3. Watchdog — 16-cycle timeout, asserts BERR open-drain 4. UART A — fixed 115200 8N1, XR68C681-compatible register map 5. GPIO / OPR — XR68C681 output port emulation; drives SPI CS, LEDs, MOSI, SCK…
