The following checklist will simplify getting your CY545 up and running.
1. Connect pin 20 to ground and pins 31 & 40 to +5 volts.
2. Be sure RESET (pin 9) is high for at least 10 milliseconds after power stabilizes. The CY545
3. Upon proper reset, all outputs should be at logic 1, and the CY545 should be testing the JOG
4. Observe the crystal frequency divided by 6 on ALE, pin 30.
The following steps may be used with the Parallel Command Interface.
5. Place the “+” command on the data bus, ASCII value 2Bh
6. Lower the IO_REQUEST line, pin 13.
7. Wait for the BUSY line to go low before bringing IO_REQUEST high again. BUSY is pin 15.
8. When IO_REQUEST is brought back high, BUSY will return high.
9. Wait for BUSY to return high, then place the carriage return code on the data bus, value 0Dh
10. Generate the IO_REQUEST handshake strobe again, interacting with the BUSY signal.
11. Upon completion of the above sequence, CCW (pin 2) will go low.
